Products

• PP 40: Pellet Press (Retsch): Benchtop hydraulic press that compacts powdered samples into solid pellets for X-ray fluorescence analysis. Pressing force is up to 40 tons. Consistent pellet density matters for XRF because a poorly formed pellet changes the measured intensity, so a controlled press is part of the analytical chain rather than an accessory.
• TG 200: Fluid Bed Dryer (Retsch): Fluid bed dryer that dries bulk material in a stream of warm air before milling or sieving, so moisture does not distort the particle size result. The material is held in suspension by the air stream, which gives short drying times and even treatment without local overheating.
• DR 100: Vibratory Feeder (Retsch): Vibratory feeder that meters pourable bulk material and fine powder into a mill, divider or analyser at a steady rate. A continuous, even feed is what makes throughput and grinding results reproducible, particularly when a mill is running unattended.
• UR Series: Ultrasonic Baths (Retsch): Ultrasonic baths for cleaning test sieves and grinding tools between samples. Removing residue from a sieve mesh matters because trapped particles change the effective aperture, and ultrasonic cleaning reaches the mesh without the mechanical damage that brushing causes.
• BB 50: Jaw Crusher (Retsch): The compact benchtop jaw crusher in the range, designed for laboratories where bench space is limited and sample quantities are small. It crushes medium hard, hard, brittle and tough material down to below 0.5 mm, with the gap width set digitally in 0.1 mm increments so a size reduction step can be reproduced exactly.
• BB 200: Jaw Crusher (Retsch): Floor standing jaw crusher aimed at fineness rather than feed size, taking medium hard, hard, brittle and tough material down to below 2 mm at up to 300 kg per hour. Grinding tools are available in several materials, so the crusher can be matched to samples where contamination from the jaws would affect the later analysis.
• BB 250: Jaw Crusher (Retsch): Jaw crusher built around ergonomic handling, with the crushing chamber and collection vessel positioned for easy access during repeated sample changes. It handles large feed pieces of medium hard, hard, brittle and tough material and reduces them to below 2 mm at up to 300 kg per hour.
• BB 300: Jaw Crusher (Retsch): Jaw crusher aimed at large feed size, accepting bigger pieces than the BB 200 and reducing them to below 5 mm at up to 600 kg per hour. The wider gap setting range suits primary crushing of rock, ore and construction material before a secondary mill takes the sample to analytical fineness.
• BB 400 XL: Jaw Crusher (Retsch): Jaw crusher combining a large feed opening with ergonomic handling, reducing medium hard, hard, brittle and tough material to below 2 mm at up to 400 kg per hour. The XL designation refers to the enlarged crushing chamber relative to the standard models.
• BB 500 XL: Jaw Crusher (Retsch): Jaw crusher with a steep crushing chamber and powerful drive, giving crushing kinematics that take 90 per cent of the product below 0.5 mm in a single pass. Throughput reaches 500 kg per hour, which suits mineral processing and cement laboratories handling continuous sample streams.
• BB 600 XL: Jaw Crusher (Retsch): The largest jaw crusher in the Retsch range, taking the biggest feed pieces and delivering the highest throughput at 3500 kg per hour. Gap width is set with spacer plates from 6 mm to 60 mm. It is used where sample volumes are at pilot plant rather than laboratory scale.
• ZM 300: Ultra Centrifugal Mill (Retsch): Rotor mill that grinds soft, medium hard, brittle and fibrous material to below 40 µm by impact and shearing between a rotor and a fixed ring sieve. Speed is freely selectable up to 23,000 rpm and the ring sieve sets the final fineness, so one mill covers a wide fineness range. Temperature monitoring protects heat sensitive samples.
• SR 300: Rotor Beater Mill (Retsch): Rotor beater mill for coarse and fine size reduction of soft to medium hard material, working by impact against a fixed beater arrangement. Speed is adjustable in 500 rpm steps so grinding can be tuned to the sample, and a ring sieve defines the final fineness down to below 50 µm.
• SK 300: Cross Beater Mill (Retsch): Cross beater mill for coarse and fine size reduction of medium hard and brittle material such as coal, coke, minerals and slag. It runs from laboratory to pilot plant scale and the adjustable rotor speed with an exchangeable bottom sieve sets the final fineness down to below 100 µm.
• HM 200: Hammer Mill (Retsch): Hammer mill for crushing and pulverising large sample volumes of medium hard, hard, brittle, tough and fibrous material at up to 1500 kg per hour. Feed material is reduced by impact from swinging hammers and passes a bottom sieve at below 0.8 mm. Its size and throughput place it between laboratory and pilot plant duty.
• SM 50: Cutting Mill (Retsch): Benchtop cutting mill for small quantities of soft, medium hard, tough, elastic and fibrous material such as plastics, textiles and plant matter. The grinding chamber design allows a high proportion of the sample to be recovered, which matters when only a small amount of material is available.
• SM 100: Cutting Mill (Retsch): Basic model cutting mill for routine size reduction of soft, medium hard, elastic and fibrous material. A fixed 1,500 rpm rotor cuts the sample against stationary knives until it passes the bottom sieve, which sets the final fineness between 0.25 mm and 20 mm.
• SM 200: Cutting Mill (Retsch): Standard cutting mill for preliminary size reduction of a wide range of soft, medium hard, tough, elastic and fibrous materials. It has a stronger drive than the SM 100 and a chamber arranged for straightforward cleaning between samples, which is the usual bottleneck when running mixed material types.
• SM 300: Cutting Mill (Retsch): High performance cutting mill with RES technology, in which a flywheel stores energy and releases it into the cut, so the rotor holds speed through tough material that would stall a conventional mill. Speed is adjustable from 100 to 3000 rpm, which lets heat sensitive samples be run slowly.
• RM 200: Mortar Grinder (Retsch): Motorised mortar and pestle that grinds, mixes and triturates soft, hard, brittle and pasty material, wet or dry, to below 10 µm. It reproduces the manual mortar process with a set pestle pressure and a fixed 100 rpm speed, so the result does not depend on who is operating it.
• DM 200: Disc Mill (Retsch): Disc mill that reduces medium hard, hard and brittle material between a fixed and a rotating grinding disc, with the gap set continuously from 0.05 mm to 5 mm. It covers both preliminary and fine grinding, and the choice of disc material governs how fine it will go and how much contamination is introduced.
• RS 200: Vibratory Disc Mill (Retsch): Vibratory disc mill that homogenises medium hard, hard, brittle and fibrous samples to below 20 µm in seconds, which is the fineness spectral analysis needs. A grinding set of rings and a puck oscillates horizontally inside a sealed jar, so the sample is not exposed and loss of fines is limited.
• RS 300 XL: Vibratory Disc Mill (Retsch): Large capacity vibratory disc mill taking batches from 35 ml up to 2,000 ml, for laboratories preparing large samples for spectral analysis. It reaches the same sub 20 µm fineness as the RS 200 but with grinding sets up to 2 litres, so a bulk sample does not have to be split before grinding.
• Emax: High Energy Ball Mill (Retsch): High energy ball mill that combines high frequency impact with intensive friction, reaching a final fineness below 80 nm. Integrated water cooling and temperature control allow long grinding runs without the sample overheating, which is what normally limits nanoscale grinding. It is used for nano grinding, mechanical alloying and colloidal milling.
• CryoMill (Retsch): Mixer mill that cools the grinding jar continuously with liquid nitrogen to minus 196 degrees Celsius during grinding, so elastic and temperature sensitive material becomes brittle enough to fracture. Cooling runs before and throughout the cycle, and the jar is cooled rather than the sample being immersed, so the sample stays dry.
• MM 400: Mixer Mill (Retsch): Multipurpose mixer mill for dry, wet and cryogenic grinding of small sample quantities, and for cell disruption in reaction vials. Two jars oscillate radially at 3 to 30 Hz, and typical grinding times are 30 seconds to 2 minutes. It also handles mixing and homogenisation, which makes it a general purpose bench unit.
• MM 500 control: Mixer Mill (Retsch): High energy mixer mill with jar temperature control from minus 100 to 100 degrees Celsius, so the thermal conditions of a grinding or mechanochemical run can be set and held. It runs at up to 30 Hz for dry, wet and cryogenic grinding, and reaches a final fineness of about 0.1 µm.
• MM 500 nano: Mixer Mill (Retsch): Mixer mill developed for producing particles in the nanometre range from batches of up to 2 x 45 ml, reaching about 0.1 µm. It supports dry, wet and cryogenic grinding as well as mechanochemistry and mechanical alloying, and the larger jar volume distinguishes it from the MM 400.
• MM 500 vario: Mixer Mill (Retsch): Mixer mill with six grinding stations, so up to 50 samples can be processed in one run when adapter racks are used. It is aimed at laboratories with a high sample count rather than a single demanding sample, and covers mechanochemistry, homogenisation, size reduction and cryogenic grinding.
• PM 100: Planetary Ball Mill (Retsch): Single station planetary ball mill in which the jar rotates about its own axis on a counter rotating sun wheel, so grinding balls are driven across the jar wall by Coriolis forces. That produces high pulverisation energy and short grinding times, down to below 1 µm and to 0.1 µm for colloidal grinding.
• PM 200: Planetary Ball Mill (Retsch): Two station planetary ball mill for grinding two samples in parallel under identical conditions, or one sample with a counterweight. Jar sizes go up to 125 ml and the mill reaches below 1 µm, and 0.1 µm for colloidal grinding. Input energy can be measured, which supports mechanochemical work.
• PM 300: Planetary Ball Mill (Retsch): Two station planetary ball mill taking jars up to 500 ml, with a higher sun wheel speed and a centrifugal acceleration of 64 g. The larger batch volume and higher energy input suit mechanochemistry and co-crystal screening as well as conventional fine grinding.
• PM 400: Planetary Ball Mill (Retsch): Floor standing planetary ball mill with four grinding stations, taking a maximum batch of 4 x 220 ml, or eight samples with stacked jars. The speed ratio can be set to 1 to minus 2, 1 to minus 2.5 or 1 to minus 3, which changes the balance between impact and friction in the grinding action.
• TM 300: Drum Mill and Bond Index Tester (Retsch): Drum mill for dry and wet grinding of soft, hard, brittle and fibrous material, with drums from 5 to 43.3 litres. Fitted with the ball or rod module it also serves as a Bond Index Tester, which is the standard way to quantify the grindability of ores and minerals ahead of plant design.
• TM 500: Drum Mill (Retsch): Large drum mill for sample volumes up to 35 litres, grinding by friction and impact down to about 15 µm. It is the unit to use when a single sample is too large for a planetary or vibratory mill, for example in cement, mining and ceramics laboratories.
• XRD-Mill McCrone (Retsch): Micronising mill developed specifically for preparing samples for X-ray diffraction. Forty eight cylindrical grinding elements arranged in the jar apply a gentle grinding action that reduces particle size below 1 µm while preserving the crystal lattice, which is what a diffraction measurement depends on.
• GrindControl: Pressure and Temperature Measuring System (Retsch): Measuring system that records pressure and temperature inside a sealed grinding jar during a run and transmits the data wirelessly. It turns a ball mill into an instrument for studying what actually happens during grinding, which matters for mechanochemical reactions where gas is evolved or consumed.
• BRILLANT 230: Cut-off Machine (QATM): Wet abrasive cut-off machine with manual wheel feed for sectioning metallographic samples up to 110 mm diameter. The aluminium body has openings on both sides so long parts can be passed through the cutting chamber, and the chamber itself is large enough for a range of clamping arrangements.
• Qcut 250 M: Cut-off Machine (QATM): Manual wet abrasive cutting machine in which the hood folds inwards on opening, leaving the whole cutting chamber accessible. A round window gives a clear view of the cut in progress. It takes wheels up to 250 mm and samples up to 90 mm diameter for short lengths.
• Qcut 250 A: Cut-off Machine (QATM): Semi-automatic abrasive cut-off machine with an automatic X axis, so it can perform pulsed cuts and oscillation cutting on large pieces as well as manual traverse cuts by hand wheel. An optional automatic cross table allows serial cutting, and the axes are monitored by travel measurement during setup and operation.
• Qcut 350 A: Cut-off Machine (QATM): Automatic wet abrasive cut-off machine for samples up to 135 mm diameter, with a low contact cutting function that reduces the thermal load on the specimen. Software features include automatic touch detection and multi-position processing, and it is used on composites and electronic assemblies as well as metals.
• Qcut 500 A: Large Cut-off Machine (QATM): Floor standing automatic cut-off machine for large components up to 190 mm diameter, with a highly dynamic axis drive and automatic traverse and chop cut functions. Feed rate is adjustable across a wide range so contact pressure can be tuned to the material.
• Qcut 600 A: Large Cut-off Machine (QATM): The largest cut-off machine in the QATM range, taking wheels up to 600 mm and workpieces up to 244 mm diameter. Automatic travel and cross feed allow low contact cutting of heavy components without repositioning by hand, and the working chamber is sized for the parts that come with that capacity.
• Qcut 200 A: Precision Cut-off Machine (QATM): Precision cut-off machine with up to three automatic axes for sectioning small and delicate samples where kerf position matters to a few micrometres. Cross feed resolution is 0.001 mm, which suits electronic components, coatings and thin sections rather than bulk metallography.
• Qtool Series: Quick Clamping Tools (QATM): Quick clamping tools that hold the specimen securely on the cutting table without slow screw adjustment between samples. Correct clamping is what prevents the specimen shifting mid cut, which would damage the wheel and ruin the section, so it is a functional part of the cutting process rather than an accessory.
• Qpress 40: Hot Mounting Press (QATM): Fully hydraulic hot mounting press with water cooling, embedding metallographic specimens in thermosetting resin. Heating and cooling times, temperature and pressure are set on an industrial touchscreen, and mould cylinders are available in several round and rectangular sizes. Advanced software adds one button operation and controlled fine dust extraction.
• Qpress 50: Hot Mounting Press (QATM): Hot mounting press in the same fully hydraulic, water cooled family as the Qpress 40, sized for the larger mould diameters. It uses the same closure system, which is designed so the mould assembly opens and closes cleanly over long service.
• Qmount: UV Mounting Device (QATM): Ultraviolet curing mounting device that sets the embedding resin with UV light instead of heat and pressure. Because there is no thermal cycle, it suits specimens that would be altered by hot mounting, and cure times are short compared with conventional cold mounting resins.
• Qpol M1 / M2: Manual Grinding and Polishing Machine (QATM): Manual single wheel (M1) and twin wheel (M2) grinding and polishing machines for laboratories preparing specimens by hand. They accept the Qpol GO head as a retrofit, so a laboratory can start manual and add semi-automatic preparation later without replacing the base machine.
• Qpol GO: Grinding and Polishing Head (QATM): Grinding and polishing head that converts a manual Qpol machine into a semi-automatic one. Single pressure and preparation time are set with rotary controls on the head itself, and the working area is lit and left visible by the slim housing.
• Qpol GO 1 / GO 2: Grinding and Polishing Machine (QATM): Automatic single wheel (GO 1) and twin wheel (GO 2) grinding and polishing machines that can run in single pressure or central pressure mode. Single pressure loads each specimen individually, which suits mixed hardness samples; central pressure loads the whole holder, which is faster for identical specimens.
• Qpol PLUS 1 / PLUS 2: Grinding and Polishing Machine (QATM): Automatic single wheel (PLUS 1) and twin wheel (PLUS 2) grinding and polishing machines with a higher performance head than the GO series, taking sample holders up to 185 mm diameter in central pressure mode. Specimens up to 50 mm diameter can be prepared, six at a time under single pressure.
• Saphir 550 / Rubin 520: Grinding and Polishing Machine (QATM): Grinding and polishing machine pairing a Saphir 550 base unit with a Rubin 520 preparation head. The head carries the sample holder and applies the load while the base drives the working wheel, so head and base can be specified to suit the throughput a laboratory needs.
• Saphir 560 / Rubin 520: Grinding and Polishing Machine (QATM): Grinding and polishing machine combining a Saphir 560 base unit with a Rubin 520 preparation head, the larger base in the Saphir line. As with the 550 combination, the head applies specimen load and the base drives the working wheel under programmed control.
• Qpol XL: Grinding and Polishing Machine (QATM): Large format grinding and polishing machine taking 300 mm and 350 mm working wheels and sample holders from 159 mm to 204 mm diameter. Both wheel and holder speeds are variable, which allows the removal rate and surface finish to be set independently.
• Qpol Vibro: Vibratory Polisher (QATM): Vibratory polisher that produces specimen surfaces with almost no residual deformation, by letting the sample move under its own weight on a vibrating cloth rather than being pressed against it. That matters for electron backscatter diffraction, atomic force microscopy and nanoindentation, where a deformed layer would mask the result.
• Qgrind XL: Planar Grinding Machine (QATM): Automatic planar grinding machine for the first, heavy removal step in specimen preparation. A ForceControl function measures removal electronically so the depth ground away is reproducible, and different grinding modes let the machine be set for maximum removal or for surface quality.
• Qetch 100 M: Electrolytic Polishing and Etching Machine (QATM): Manual electrolytic polisher and etcher that removes material by anodic dissolution rather than abrasion, giving a deformation free surface on metals that smear or work harden under mechanical polishing. The same unit performs electrolytic etching to reveal the microstructure.
• Qetch 1000: Electrolytic Polishing and Etching Machine (QATM): Electrolytic polishing and etching machine with programmable parameter control, so voltage, current and time can be stored per material and recalled. It covers the same anodic dissolution process as the Qetch 100 M with the reproducibility that stored settings give.
• Qness 10 / 60 M: Micro Hardness Tester (QATM): Manual micro hardness tester covering Vickers, Knoop and Brinell, with Rockwell as an option. Force is applied electronically and the test sequence runs automatically once the indent position is set. An eight position motorised turret carries up to three testing modules and seven lenses, so the tester doubles as a metallurgical microscope.
• Qness 10 / 60 A+: Micro Hardness Tester (QATM): Fully automatic micro hardness tester with a motorised XY cross slide, so hardness traverses and case depth profiles run without operator intervention. Positioning accuracy is 2 micrometres and the table travel can be extended to 300 by 150 mm for larger specimens.
• Qness 60 A+ EVO: Micro Hardness Tester (QATM): The EVO generation of the automatic micro hardness tester, with positioning accuracy improved to 0.2 micrometres. That resolution matters for closely spaced indent series such as case hardening depth measurements, where indent spacing rules limit how near indents may be placed.
• Qness 150 CS: Rockwell Hardness Tester (QATM): Compact Rockwell hardness tester with a C shaped frame, a fixed test head and a spindle that raises the specimen to the indenter. Force is applied electronically and the sequence runs automatically, with results shown on a 7 inch touchscreen. It complies with DIN EN ISO 6508 and ASTM E-18.
• Qness 150 CSA+: Rockwell Hardness Tester (QATM): Rockwell hardness tester with a fully automatic XY slide, combining the speed of a dedicated Rockwell machine with automated series testing. It suits parts of identical test height where a defined pattern of indents is required, and single tests can still be run manually.
• Qness 60 / 150 RCS: Rockwell Hardness Tester (QATM): Production line Rockwell hardness tester with a test cycle under two seconds, controlled by a Siemens S7 with a 4 inch touch display. It is built to be integrated into a production line for in-process hardness checking, with results output over an RS232 interface.
• Qness 200 CS: Macro Hardness Tester (QATM): Compact universal macro hardness tester with a five position turret carrying indenters and lenses. The fixed head and moving spindle arrangement gives a 250 mm test height with a 238 mm throat, so reasonably large parts can be tested without a special fixture.
• Qness 250 / 750 / 3000 C and CS EVO: Universal Hardness Tester (QATM): Universal hardness testers covering Brinell, Vickers, Rockwell, Knoop and plastics methods, in three force classes up to 3000 kg. The C shaped frame with fixed head and moving spindle gives a 395 mm test height, and an eight position tool changer is available in place of the standard two positions.
• Qness 250 / 750 / 3000 E EVO: Macro Hardness Tester (QATM): Macro hardness testers with an extra large fixed test table and a motorised test head, so very large components can be tested without lifting them onto a spindle. Test height reaches 510 mm and the table measures 584 by 450 mm, which puts heavy fabricated parts within reach.
• Qness 250 / 750 / 3000 A+ EVO: Fully Automated Macro Hardness Tester (QATM): Fully automated macro hardness testers with three axis control, so specimens of differing test height can be measured in one run without refixturing. A Jominy sample holder with test module is available as an option for end quench hardenability testing.
• BELCAT II: Catalyst Analyser (Microtrac MRB): Chemisorption and temperature programmed analyser for catalyst characterisation, covering temperature programmed desorption, reduction and oxidation as well as pulse chemisorption. These measurements give active metal surface area and dispersion, which is what determines catalyst activity.
• BELMASS II: Quadrupole Mass Spectrometer (Microtrac MRB): Quadrupole mass spectrometer that couples to the BELCAT analyser to identify the gases evolved during a temperature programmed experiment. Without it a thermal conductivity trace shows that something desorbed; with it, what desorbed can be named.
• BELMETAL 3: Metal Dispersion Rate Analyser (Microtrac MRB): Analyser dedicated to measuring metal dispersion in supported catalysts, that is the fraction of metal atoms exposed at the surface and therefore available to react. It is a focused instrument for catalyst development where dispersion is the number being optimised.
• AS 200 basic: Vibratory Sieve Shaker (Retsch): Entry level vibratory sieve shaker for dry and wet sieve analysis on 100 mm, 200 mm and 203 mm sieves. The electromagnetic drive produces a three dimensional throwing motion with angular momentum, so material is distributed evenly across the whole mesh. Amplitude and sieving time are set on an analogue panel, making it a straightforward choice for routine grading work.
• AS 200 digit cA: Vibratory Sieve Shaker (Retsch): Standard vibratory sieve shaker with digital setting and electronic control of the sieving amplitude, so the same amplitude is held whatever the mass of the sieve stack. Suitable for dry and wet sieving of powders, bulk materials and suspensions. Sieving time is set digitally and interval operation can be selected.
• AS 200 control: Vibratory Sieve Shaker (Retsch): Quality control sieve shaker with digital setting and control of every sieving parameter and memory for 99 standard operating procedures. The patented electromagnetic drive gives a three dimensional throwing motion, and sieve acceleration is held independent of mains frequency so results are reproducible between laboratories. It handles dry and wet sieving and carries a test certificate, and it can be calibrated.
• AS 300 control: Vibratory Sieve Shaker (Retsch): Vibratory sieve shaker built for the larger 305 mm and 315 mm sieve diameters used for aggregate and construction material grading. It uses the same controlled electromagnetic three dimensional drive as the AS 200 control, with digital parameter setting and SOP memory. Dry and wet sieving are both supported.
• AS 400 control: Horizontal Sieve Shaker (Retsch): Horizontal sieve shaker that moves the sieve stack in a circular motion in the horizontal plane. That action suits needle shaped, flat, long or fibrous particles and abrasives, where a throwing motion would give a poor separation. It takes sieve diameters up to 400 mm, so it covers coarse aggregate fractions.
• AS 450 basic: Vibratory Sieve Shaker (Retsch): Large capacity vibratory sieve shaker for 400 mm and 450 mm sieves, giving up to 10 fractions in a single sieving run. Amplitude is set in steps rather than continuously, which makes it the budget alternative to the AS 450 control for laboratories handling large sample volumes of sand, aggregate and other bulk material.
• AS 450 control: Vibratory Sieve Shaker (Retsch): The largest vibratory sieve shaker in the Retsch range, using controlled electromagnetic tapping technology to drive sieve stacks of up to 25 kg. It accepts 400 mm and 450 mm sieves and covers a measuring range from 25 µm to 125 mm, which takes in coarse aggregate as well as fine fractions. Amplitude is digitally set and held constant regardless of load.
• AS 200 jet: Air Jet Sieving Machine (Retsch): Air jet sieving machine for fine powders that agglomerate or will not pass a mesh under vibration alone. A rotating slotted nozzle blows a jet of air up through the mesh to disperse the sample while a vacuum draws the undersize away, so each cut is made on a single sieve rather than a stack. It is used where a conventional vibratory shaker cannot disperse the material.
• AS 200 jet pro / AS 200 jet pharma: Air Jet Sieving Machines (Retsch): Air jet sieving machines that combine sieving and weighing in one instrument, so the sieve does not have to be removed between fractions. The pharma version adds audit trail functionality for regulated laboratories. Both work on the rotating air jet principle for fine powders that will not disperse under vibration.
• AS 200 tap: Tap Sieve Shaker (Retsch): Tap sieve shaker that mechanises the manual sieving procedure specified in several national standards, superimposing a vertical tapping action on a horizontal circular motion. It is used where a standard calls for tapping rather than vibration, and gives the reproducibility of a machine in place of hand sieving.
• Woven Wire Mesh Test Sieves, 200 mm / 203 mm diameter (Retsch): Woven wire mesh test sieves in the 200 mm and 203 mm (8 inch) frame diameters that most laboratory sieve shakers are built around. The mesh is tensioned into a stainless steel frame and the sieves are supplied to ISO 3310-1 and ASTM E11, with inspection, calibration or certified quality options depending on the level of documentation a laboratory needs.
• Woven Wire Mesh Test Sieves, other frame diameters (Retsch): Woven wire mesh test sieves in 100 mm, 305 mm, 400 mm and 450 mm frame diameters for shakers outside the standard 200 mm format. The 305 mm and larger frames suit aggregate and construction material grading where sample masses are high, while the 100 mm frame is used where sample quantity is limited.
• Perforated Plate Test Sieves (Retsch): Test sieves made from perforated metal plate rather than woven mesh, used for the coarse fractions where a woven cloth would distort. Round and square apertures are available, and the sieves are supplied to ISO 3310-2 and ISO 5223 in 200 mm, 305 mm and 400 mm frame diameters.
• Test Sieve Accessories (Retsch): Supporting items for sieve analysis, including collecting pans, intermediate pans, lids, spacer rings, sieving aids for materials that blind the mesh, and test sieve racks for storage. These are the consumable and ancillary parts that a sieve laboratory needs alongside the shaker and the sieves themselves.
• SieveCare: Test Sieve Cleaning, Inspection and Recalibration Service (Retsch): Service programme for test sieves in use, covering ultrasonic cleaning, optical inspection of the mesh and recalibration against the relevant standard. It is how a laboratory keeps documented evidence that its sieves still meet ISO 3310 after months of use.
• PT 100: Sample Divider (Retsch): Rotating sample divider that splits a bulk sample into equal representative sub-samples, so what reaches the analytical instrument reflects the whole consignment. It handles pourable solids with a feed size up to 10 mm and can be set to 6, 8 or 10 divisions depending on the head fitted.
• PT 200: Rotating Tube Divider (Retsch): Rotating tube divider for powdered and granular bulk materials with a feed size up to 10 mm. The dividing ratio is set by the bottom cone fitted, giving one, two or three fractions, which suits laboratories that need a specific split ratio rather than a fixed number of equal parts.
• PT 300: Rotating Sample Divider (Retsch): Rotating sample divider for dust free division and volume reduction of large quantities of powdered or granular bulk material, with a feed size up to 30 mm. It can be set to 4, 6, 8 or 10 divisions, or configured to reject part of the stream, which is how large field samples are cut down to laboratory size.
• RT 6.5 to RT 75: Sample Splitter (Retsch): Riffle sample splitters that halve a sample by passing it through alternating chutes, the classic method described in DIN 51701. The series runs from RT 6.5 to RT 75 with slot widths matched to feed sizes from about 4 mm to 50 mm, and requires no power supply.
• RT 100: Sample Splitter (Retsch): Riffle sample splitter with an adjustable slot width, so one unit covers a range of feed sizes instead of needing a different splitter for each. Slot width is adjustable from 12 mm to 108 mm and it divides the sample in two. It is built for laboratory and on-site use.
• TWISTER: Cyclone Mill (Retsch): Cyclone mill developed for preparing food and feed samples ahead of near infrared analysis. A cyclone separator draws the ground material out of the grinding chamber quickly, which limits heating and moisture loss, both of which would otherwise shift the NIR result. Final fineness is below 250 µm.
• GRINDOMIX GM 200: Knife Mill (Retsch): Knife mill for preparing food and feed samples, homogenising material that contains water, fat or oil as well as dry and fibrous samples. Two blade speeds allow coarse cutting then fine homogenisation in one vessel, and a boost setting raises speed to 14,000 rpm for the final stage.
• GRINDOMIX GM 300: Knife Mill (Retsch): Large capacity knife mill taking batches up to 4500 ml, for food and feed samples that need to be homogenised in bulk rather than in sub-samples. All parts that touch the sample are autoclavable, which matters where microbiological testing follows the milling step.
• System Laboratory: Metallographic Laboratory Furniture (QATM): Modular laboratory furniture designed around metallographic preparation, with work surfaces, framework, handles and high pressure laminate decor specified for the wet and abrasive conditions of a sample preparation room. QATM provide 3D planning software so a layout can be reviewed before it is built.
• Qeye 200 / Qeye 800: Optical Analyser and Inverse Macroscope (QATM): Inverse macroscopes for visual quality control of weld seams, solder joints and components, working directly on the macro section. The Qeye 200 has the finer field of view for laser welds and electronic assemblies; the Qeye 800 covers the larger fields used for macro welds in steel fabrication. Both assess weld shape, penetration depth and defects to DIN EN ISO 5817.
• EasySieve pro / EasySieve pharma: Sieve Analysis Evaluation Software (Retsch): Software that records sieve weights straight from a connected balance and produces the particle size distribution without manual transcription. It controls the sieve shaker, stores standard operating procedures and generates the grading report. The pharma version adds the record keeping features regulated laboratories require.
• Qpix T2 and Qpix Control2: Hardness Testing Software (QATM): Software for QATM hardness testers, from Qpix T2 on the touchscreen models through Qpix Control2 for automated testing and the Control2 M and R variants that add microscopy and reporting functions. It handles test sequence definition, indent evaluation, series and traverse programmes and result documentation.
• Q AI: Automatic Indent Evaluation Software (QATM): Machine learning module that evaluates hardness indents automatically, including the difficult surfaces where conventional edge detection struggles. It runs inside the Qpix environment and is aimed at removing operator to operator variation in reading indent diagonals.
• ELEMENTS: Elemental Analyser Software (Eltra): Control and evaluation software for the ELEMENTRAC generation of Eltra analysers, handling method setup, calibration, result filtering and report generation. It is the operating layer of the instrument rather than an optional add-on.
• ELEMENTS Cloud: Remote Instrument Management (Eltra): Cloud service that lets an ELEMENTRAC analyser be monitored and managed remotely, so instrument status and results can be seen from outside the laboratory. It is aimed at organisations running several analysers across sites.
• DIMENSIONS: Measurement and Evaluation Software (Microtrac MRB): Control and evaluation software for Microtrac particle size and shape analysers, handling measurement setup, result calculation and reporting. It presents laser diffraction and image analysis data in one environment, which matters on the SYNC where both are acquired together.
• BELCONTROL: Operation Software for BELSORP Series (Microtrac MRB): Common operating software for the BELSORP adsorption analysers, running measurement sequences and calculating surface area, pore size distribution and related quantities from the isotherm. One interface covers the whole BELSORP range.
• Dissolution Tester Software Disso.NET 4 (Erweka): Disso.NET 4 is Erweka's 21 CFR Part 11 compliant companion to all their dissolution systems, from offline systems through online and on/offline systems up to the fully automated RoboDis II+. It handles standard dissolution jobs and qualification tasks, and gives control over every single function of the connected devices such as a dissolution tester with a UV-Vis spectrophotometer. Once tests finish the software creates extensive reports carrying corporate logos for PDF export, or exports results in XLS or XML. Its Audit Trail documents what, who, when and why for every change made to the system and can be searched and filtered in the Audit Trail Viewer, and an Active Directory connection allows cross system login data and passwords.
• Physical Tester Software MC.NET (Erweka): MC.NET is Erweka's software for external control of their hardness and combination testers, covering everything from the compact TBH 325 and TBH 425 through to the fully automated EasyCheck and MultiCheck 5, 5.1 and 6. Data from multiple devices can be held in a single networked MS SQL database and reached from several MC.NET installations on the same network, with advanced Audit Trail features maintaining data integrity. Users can qualify devices, create and use methods and analyse test results, all with full 21 CFR Part 11 conformity. An electronic signature removes the need for handwritten approval, taking creation, audit and approval of test results into the software, and user management works with the network database and supports Active Directory.
• Physical Tester Software Export Manager (Erweka): Export Manager gives simple and fast data export from Erweka instruments. The Windows software is installed on any PC within the laboratory network, where it receives test reports from devices such as the SVM II, TAR II, EasyCheck, MultiCheck 6, ZT 720/30 or TBH II and converts them automatically into PDF and XML files, doing away with manual scanning of printed reports. The destination folder can be a local drive or a specific network location, so the security measures and data compliance protocols that already apply to the network apply to those folders too. Each exported file is named with the device type, serial number and the date and time the data was received, and the software can receive data from several devices at once.
• ELEMENTRAC CS-i: Carbon / Sulphur Analyser (Eltra): Induction furnace carbon and sulphur analyser for inorganic samples such as steel, cast iron, ores and ceramics. The sample is burned above 2,000 degrees Celsius in oxygen and the resulting carbon dioxide and sulphur dioxide are measured by solid state infrared absorption. A heated dust trap and a platinum based catalyst reactor handle the dusty combustion products that these materials produce.
• ELEMENTRAC CS-r: Carbon / Sulphur Analyser (Eltra): Horizontal resistance furnace analyser for carbon and sulphur in organic samples, using ceramic boats that allow a high sample weight. The infrared path is made of solid gold, which resists the halogen and acid combustion products that corrode aluminium cells. Furnace temperature is adjustable to 1550 degrees Celsius in one degree steps.
• ELEMENTRAC CS-d: Carbon / Sulphur Analyser (Eltra): Dual furnace analyser carrying both an induction furnace and a resistance furnace, so organic and inorganic samples can be run on the same instrument without changing configuration. Up to four independent infrared cells cover different concentration ranges, and the gold infrared path extends cell life on halogen bearing samples.
• CS-580A: Carbon / Sulphur Analyser (Eltra): Vertical resistance furnace analyser for simultaneous carbon and sulphur determination in organic samples, and for total organic and total inorganic carbon. It can be configured for a single element or for both, and an autoloader with 36 or 130 crucible positions is required for unattended running.
• ELEMENTRAC CHS-r: Carbon / Hydrogen / Sulphur Analyser (Eltra): Horizontal resistance furnace analyser measuring carbon, hydrogen and sulphur simultaneously in organic samples, to DIN, EN and ISO methods. Ceramic boats allow a high sample weight, which matters for heterogeneous material such as coal, coke and biomass where a small aliquot would not be representative.
• CHS-580A: Carbon / Hydrogen / Sulphur Analyser (Eltra): Vertical furnace analyser for simultaneous carbon, hydrogen and sulphur determination in organic samples, configurable for single element or multi-element operation. As with the CS-580A it uses ceramic crucibles and an autoloader, and covers total organic and total inorganic carbon.
• CW-800: Carbon Dioxide / Water Analyser (Eltra): Analyser that determines carbon dioxide and water content simultaneously in materials such as cement and gypsum. A quartz tube resistance furnace runs at a fixed temperature up to 1000 degrees Celsius under nitrogen, and the released gases are measured by infrared absorption through a gold path, so no halogen trap is needed.
• CW-800M: Carbon / Water Analyser (Eltra): Fractional carbon and water analyser that steps the furnace through up to five programmed temperatures in one run, so total organic and total inorganic carbon can be separated by their release temperature rather than by acid treatment. Maximum sample size is 32 by 145 mm in a quartz boat.
• SurfaceC-800: Surface Carbon Analyser (Eltra): Analyser that determines carbon present on the surface of solid samples, as distinct from bulk carbon. Both furnace temperature and carrier gas can be changed during the measurement to a user defined programme, which is how surface residues are driven off and measured separately from carbon in the matrix.
• ELEMENTRAC ONH-ps: Oxygen / Nitrogen / Hydrogen Analyser (Eltra): Simultaneous oxygen, nitrogen and hydrogen analyser for inorganic samples, using an electrode impulse furnace that exceeds 3,000 degrees Celsius in a graphite crucible. Oxygen and hydrogen are measured by infrared absorption and nitrogen by thermal conductivity. The closed gas system keeps consumption low, and argon can be used as carrier gas in place of helium.
• ELEMENTRAC ONH-p: Oxygen / Nitrogen / Hydrogen Analyser (Eltra): Impulse furnace analyser measuring oxygen, nitrogen and hydrogen concentrations in inorganic materials such as steel, non-ferrous metals and ceramics. It uses the hot extraction principle, in which the sample is fused in a graphite crucible and the gases released are carried to infrared and thermal conductivity detectors.
• ELEMENTRAC OH-p: Oxygen / Hydrogen Analyser (Eltra): Impulse furnace analyser configured for oxygen and hydrogen only, for laboratories that do not need nitrogen determination. Removing the nitrogen channel simplifies the gas handling and shortens the analysis, while keeping the same hot extraction principle in a graphite crucible.
• ELEMENTRAC ON-p: Oxygen / Nitrogen Analyser (Eltra): Impulse furnace analyser for oxygen and nitrogen in inorganic materials. Oxygen is measured as carbon dioxide by infrared absorption and nitrogen by thermal conductivity, following fusion of the sample in a graphite crucible. It suits steel and non-ferrous metal laboratories where hydrogen is not part of the specification.
• ELEMENTRAC H-r: Hydrogen Analyser (Eltra): Dedicated hydrogen analyser using the hot extraction method, in which the sample is heated below its melting point so diffusible hydrogen is released without fusing the matrix. It is used on steel and iron, where hydrogen content governs susceptibility to cracking.
• ELEMENTRAC CN-r: Carbon / Nitrogen / Protein Analyser (Eltra): Dumas combustion analyser for carbon and nitrogen, with protein calculated from the nitrogen result. It is the alternative to Kjeldahl digestion for food, feed, soil and fertiliser laboratories, and avoids the concentrated acid and catalyst that the wet method requires.
• TGA THERMOSTEP: Thermogravimetric Analyser (Eltra): Macro thermogravimetric analyser that determines moisture, volatile matter, ash and loss on ignition in a single programmed run by weighing samples continuously as the furnace steps through temperature stages. Up to 19 samples are carried on a carousel, which suits coal, coke, biomass and mineral laboratories running proximate analysis.
• Consumables for Elemental Analysers (Eltra): Crucibles, ceramic and quartz boats, reagents, catalysts and furnace parts for Eltra analysers. Combustion analysis consumes these on every run, and the grade of crucible and reagent affects the blank value, so they form part of the analytical method rather than general supplies.
• CAMSIZER 3D: Particle Size and Shape Analyser (Microtrac MRB): Dynamic image analyser that photographs particles in free fall with two cameras and derives size, shape, volume, density, transparency and count from the images. Working to ISO 13322-2, it covers a recommended range from 20 µm to 30 mm with no hardware change, which suits granules, tablets, aggregates and abrasives.
• CAMSIZER X2+: Particle Size and Shape Analyser (Microtrac MRB): Dynamic image analyser for fine powders, covering 0.9 µm to 8 mm with a digital resolution of 0.9 µm per pixel. Three dispersion options are built in, air pressure, gravity and wet, so cohesive powders and suspensions can both be measured on the same instrument. Shape parameters follow ISO 9276-6.
• CAMSIZER XL: Particle Size and Shape Analyser (Microtrac MRB): Large particle image analyser covering 160 µm to 135 mm, so it reaches into the size range normally handled by sieving. That makes it directly relevant to aggregate, fertiliser and mineral grading, where it produces size and shape data from a sample of a few kilogrammes in minutes.
• CAMSIZER S1: Particle Size and Shape Analyser (Microtrac MRB): Benchtop dynamic image analyser in the CAMSIZER family, aimed at laboratories that need image based size and shape data in a smaller footprint than the X2+ or 3D. It works on the same free fall imaging principle to ISO 13322-2.
• CAMSIZER ONLINE: In-Process Particle Size and Shape Analyser (Microtrac MRB): Process version of the CAMSIZER, built into a stainless steel housing so it can be mounted in a production loop and measure size and shape continuously rather than on grab samples. It covers 30 µm to 30 mm for dry free flowing powders, granulates and bulk material.
• CAMSIZER ONLINE XL: In-Process Particle Size and Shape Analyser (Microtrac MRB): The large size version of the process CAMSIZER, covering 160 µm to 135 mm for coarse bulk material moving on a production line. It uses the same imaging principle and stainless steel construction as the standard ONLINE unit in a larger frame.
• S3500: Particle Size Analyser (Microtrac MRB): Laser diffraction particle size analyser using three precisely positioned red laser diodes rather than a single beam, which extends the angular coverage without moving optics. It measures from 0.02 µm to 2.8 mm in ten to thirty seconds and reports volume, number and area distributions.
• BLUEWAVE: Particle Size Analyser (Microtrac MRB): Laser diffraction analyser that adds two blue 405 nm lasers to the red source, because the shorter wavelength improves resolution at the fine end. It measures from 0.01 µm to 2.8 mm and applies Mie theory for spherical particles with a modified Mie calculation for non-spherical ones.
• SYNC: Combined Laser Diffraction and Dynamic Image Analyser (Microtrac MRB): Analyser that runs laser diffraction and dynamic image analysis on the same sample stream at the same time, so size distribution and shape data come from one measurement rather than two instruments. It covers 0.01 to 4000 µm and works to ISO 13320 and ISO 13322-2 together.
• AEROTRAC II: Spray Particle and Droplet Size Analyser (Microtrac MRB): Laser diffraction analyser configured for airborne particles and droplets, measuring sprays, mists and atomised liquids in flight. Three interchangeable lenses cover 0.5 µm to 2000 µm, and spray measurements can be as short as 0.02 milliseconds to capture a single pulse.
• NANOTRAC FLEX: Nanoparticle Size Analyser (Microtrac MRB): Dynamic light scattering analyser using an external probe rather than a cuvette, so measurements can be taken in situ in a reaction vessel or process line. It covers 0.3 nm to 10 µm and works at sample concentrations up to 40 per cent, which removes the dilution step that normally distorts a DLS result.
• NANOTRAC WAVE II: Nanoparticle Size and Zeta Potential Analyser (Microtrac MRB): Dynamic light scattering analyser that measures particle size, zeta potential, concentration and molecular weight in one benchtop instrument. Combining size and charge in a single measurement is useful for colloid and formulation work, where stability depends on both together.
• STABINO ZETA: Zeta Potential Analyser (Microtrac MRB): Zeta potential analyser based on the streaming potential principle, a mechanical measurement rather than an optical one, so it works on concentrated and opaque dispersions where electrophoretic light scattering fails. It performs fast titrations and measures pH and conductivity alongside charge.
• TURBISCAN LAB: Stability Analyser (Microtrac MRB): Stability analyser that scans a sample vial with an 880 nm beam and records transmitted and backscattered light along its whole height, so sedimentation, creaming, flocculation and coalescence are detected before they are visible. The sample is measured undiluted and undisturbed in its native state.
• TURBISCAN TOWER: Multi-Sample Stability Analyser (Microtrac MRB): Multi-sample version of the Turbiscan stability analyser, holding several vials in a temperature controlled tower so a formulation series can be aged and scanned in parallel. It uses the same static multiple light scattering measurement as the LAB model.
• TURBISCAN TRILAB: Multi-Sample Stability Analyser (Microtrac MRB): Stability analyser combining multi-sample scanning with additional characterisation channels, so more than one property of a dispersion can be followed over the same ageing period. It is aimed at formulation laboratories comparing several candidate recipes.
• TURBISCAN AGS: High-Throughput Stability Analyser (Microtrac MRB): High throughput stability analyser with an ageing station, so samples are held at a controlled temperature and scanned automatically over days or weeks without an operator. That turns shelf life prediction into an unattended experiment.
• TURBISCAN DNS: Dispersibility and Stability Analyser (Microtrac MRB): Analyser that measures how readily a powder disperses into a liquid as well as how stable the resulting dispersion is, by scanning the vessel while dispersion takes place. Dispersibility and stability are separate properties, and this instrument records both in the same run.
• BELSORP MINI X: BET Specific Surface Area and Pore Size Analyser (Microtrac MRB): Volumetric gas adsorption analyser for BET specific surface area and pore size distribution, the routine workhorse of the BELSORP range. It measures nitrogen or other gas uptake at cryogenic temperature and derives surface area and pore structure from the isotherm.
• BELSORP MAX X: High-Precision Gas and Vapour Adsorption Analyser (Microtrac MRB): High precision adsorption analyser handling vapours as well as permanent gases, so water, organic solvent and other vapour isotherms can be measured alongside nitrogen. It is the research grade instrument in the BELSORP line, used for micropore analysis and adsorbent development.
• BELSORP MAX G: High-Precision Gas Adsorption Analyser (Microtrac MRB): High precision gas adsorption analyser for surface area and pore size distribution, configured for permanent gases rather than vapours. It sits between the MINI X and the MAX X, giving research grade precision for laboratories that do not need vapour capability.
• BELSORP MR1: BET Surface Area Analyser (Microtrac MRB): Single point and multipoint BET surface area analyser aimed at routine quality control rather than full isotherm research. Where a laboratory only needs a specific surface area figure per batch, it gives that result faster than a full volumetric instrument.
• BELCRYO X: High-Precision Cryogenic Unit (Microtrac MRB): Cryogenic temperature control unit for BELSORP adsorption analysers, replacing the liquid nitrogen dewar with a closed cycle cooler. It removes the need to refill coolant during long isotherm runs and holds the adsorption temperature more steadily than an evaporating bath.
• BELSORP HP: High Pressure Gas Adsorption Instrument (Microtrac MRB): High pressure adsorption instrument for measuring gas uptake well above atmospheric pressure. That is the regime that matters for hydrogen and methane storage, for carbon dioxide capture and for screening adsorbents used in gas separation. Isotherms are measured volumetrically, as on the other BELSORP instruments, but with a pressure range that ordinary surface area analysers do not reach.
• BELPORE Series: Mercury Porosimeter (Microtrac MRB): Mercury intrusion porosimeter that forces mercury into a porous solid under increasing pressure to derive pore size distribution and total pore volume. It covers the macropore and mesopore range that gas adsorption cannot reach, and is used on ceramics, catalysts, cements and rock.
• BELPYCNO: Density Analyser (Microtrac MRB): Gas pycnometer that determines true density of powders and porous solids by measuring the volume of gas that the sample displaces, so open pores are excluded from the volume. Helium is normally used because its small molecule penetrates fine pore structures.
• BELPYCNO L: Gas Pycnometer (Microtrac MRB): Larger chamber version of the BELPYCNO gas pycnometer, for samples too bulky for the standard cell. It uses the same gas displacement principle to give true density excluding open porosity.
• BELPREP VAC II: Vacuum Degasser (Microtrac MRB): Vacuum degassing station that removes adsorbed moisture and gases from samples before an adsorption measurement. Incomplete degassing is the commonest source of error in BET surface area work, because residual water occupies the sites the measurement is meant to count.
• BELPREP VAC III: Vacuum Degasser (Microtrac MRB): The current generation vacuum degasser in the BELPREP line, preparing samples for gas adsorption analysis by heating them under vacuum until adsorbed species are removed. It is used ahead of BET surface area and pore size measurements.
• Digital Dissolution Tester DT 950 Series (DT 956, DT 957, DT 958) (Erweka): Erweka's DT 950 is an advanced digital dissolution tester built on embedded PC technology, with a 7 inch touch display, an intuitive user interface and a fully integrated Audit Trail for 21 CFR Part 11 compliance. TestAssist guides the operator step by step through test configuration so only compliant parameters are entered for USP / EP / JP conform dissolution testing. Method Management allows methods to be created, edited and approved, User Management handles access control and rights, and data export to FTP servers gives LIMS connectivity. The system can be upgraded from 6 to 8 test stations, fitted with automatic tablet drop or temperature sensors for each vessel, and switched between low head and high head modes.
• Digital Dissolution Tester DT 9510 Series (DT 9512, DT 9513, DT 9514) (Erweka): Erweka describe the DT 9510 series as the big brother of the DT 950. It is driven by the same integrated PC, and its up to 14 test stations run from a single powerful motor while the large water bath holds temperature steady through the thermal inertia of the water. That allows two batches of samples to be tested in parallel under exactly the same conditions, 100 % USP / EP compliant. The optional AirLift system raises and lowers the dissolution head at the press of two buttons, with a two hand safety arrangement that stops the movement as soon as either button is released. TestAssist and automatic tablet drop are carried over from the smaller model.
• Dissolution Tester DT Light Series (DT 126 Light, DT 128 Light) (Erweka): The DT Light series packages proven Erweka quality for a small budget, covering simple dissolution tests to USP methods 1, 2, 5 and 6. Units carry 6 or 8 test stations and a fixed high head drive that keeps each 1000 ml vessel easy to reach. Shafts change over quickly and the one piece moulded PET water bath uses the established Erweka water outlet for straightforward cleaning, while an external flow through heater reduces the influence of vibration and holds a stable temperature. Every accessory that touches the dissolution sample is fitted in Germany, so the series carries Erweka's Made in Germany quality.
• Dissolution Tester BioDis RRT 10 (USP 3 / USP 7) (Erweka): The RRT 10 automates dissolution testing for extended and sustained release dosage forms and is suited to simulating the pH changes within the human body. Placing a different medium in each row lets the instrument mirror varying gastrointestinal conditions in vivo, and automatic sample transport between rows supports reliable release testing across different pH zones. Erweka supply it as a USP method 3 device, a USP method 7 device, or a combination of both, with an external flow through heater that minimises vibration and a detachable touch display. Vessels sit in an acrylic water bath with an outlet valve for cleaning, and an automatic cover system reduces evaporation of the media.
• Flow-Through Cell DFZ II (USP 4) (Erweka): Erweka's DFZ II flow through cell tester covers a wide range of applications thanks to the variety of cell types available, including testing of poorly soluble products and low dose sustained release formulations. A cell design with increased leak tightness and an optimised tubing system with quick locks let tests be prepared and run quickly. The standardised cell head fits every cell body on offer and, with flat gaskets reduced to three parts per cell, handling and installation are simplified. Cell bodies have reduced wall thickness for improved warming and each cell can be heated individually via a rotary switch. All USP 4 DFZ II systems are controlled through a controller running Disso.NET 3.X software.
• Chewing Gum Tester DRT (Erweka): The DRT tests in vitro release of substances from chewing gums and other dosage forms that have to be masticated into the surrounding liquid medium. Vertical up and down strokes of the lower jaw combine with a revolving movement of the upper jaw to give ideal mastication of the gum and simultaneous agitation of the test medium. For manual sampling, emptying and cleaning, the lower jaw with the test cell lowers so that the chewing process stops, after which the test cell and both jaws lift out easily. A water circulation system regulates the water temperature in the test cell around the media. The modular design allows any number of gums to be tested, with 6 test stations the most commonly used, and cells can take extra accessories to measure chewing gum pressure, torque at shear force, pH value and temperature.
• Media Preparation MediPrep Series (MediPrep 820, MediPrep 1622) (Erweka): The MediPrep 820 prepares up to 8 litres of dissolution media in under 15 minutes, while the MediPrep 1622 takes just 25 minutes and is three times faster than manual preparation to USP. Media are mixed, heated, degassed and gravimetrically filled into vessels in a single pass, and foaming media such as SDS can be handled. Filling runs through the integrated dosing connection or directly into containers with the optional remote filling hand. The MediPrep 1622 adds two inlets for premixed media and a waste water outlet, together with an integrated automatic cleaning process that prevents cross contamination.
• Digital Dissolution Offline System, DT 950 and DT 9510 Series (Erweka): This offline system extends the DT 950 and DT 9510 series with the first step in dissolution automation: fully automated sampling and storage in vials for separate analysis. The updated TestAssist lets the operator configure and start dissolution tests with automatic sampling from the 7 inch touch display, guiding the user through the test in a few steps for 100 % USP / EP / JP compliant work. User management configures individual rights, so functions can be restricted to administrators, operators and service technicians. Erweka describe it as their most advanced stand alone dissolution system and an easy entry point into dissolution automation.
• Dissolution Online System UV-Vis (Erweka): Erweka's dissolution online systems are a semi automatic solution for dissolution testing with automated UV/VIS online analysis. The DT 950 with its integrated, automated ASS-9 sampling station carries freshly sampled media straight to the UV/VIS analyser, where samples are measured and results stored in Erweka's Disso.NET software. Analysers offered include the Mettler Toledo UV7, the Shimadzu 1900i Plus, the Analytik Jena Specord 200/210 Plus and the Thermo Fisher Evolution Pro, each combined with the DT 950 and either an IPC 8 peristaltic pump or a PVP piston pump. Every component is controlled from the Disso.NET PC software.
• Dissolution On-/Offline System with UV-Vis (Erweka): A semi automated dissolution system with connected UV-Vis measurement and sample collection, controlled by Disso.NET. Erweka present it as the ideal configuration for spectrophotometers: the attached PC runs the whole system through the Disso.NET software, which also gives full control over all components. Once analysis finishes, samples are stored using Erweka's own FRL 6/7/854 sample collector.
• Dissolution HPLC On-/Offline System (Erweka): Erweka's HPLC on/offline system is the semi automated route to 100 % USP / EP / JP compliant dissolution testing with HPLC online analysis. Up to 5 of the 8 dissolution steps can be automated by pairing a DT 950 or DT 9510 series tester with CTC sampling and online HPLC chromatography, the whole set controlled by Disso.NET. For filtration at 0.45 µm the automatic filter changer AFC 825 works alongside the maintenance free PVP pump, with other filter sizes available on request. After the dissolution test and double filtration with the PVP 820 pump and the AFC 825, medium is transferred to the HPLC sampler, filled into a PEEK transfer block and distributed into vials, where samples can be diluted for immediate analysis or cooled and shielded from UV radiation for later analysis.
• Fully Automated Dissolution System RoboDis II+ (Erweka): Erweka state that the RoboDis II+ is the only simultaneously operating, fully automatic dissolution test system currently on the market, with every stage of the dissolution process computer controlled and carried out without user intervention. Disso.NET is the key element, controlling all system functions including precise movement of the robot arm, control of the analysers, data processing and full documentation. In standard configuration it tests up to 10 batches to USP method 1 (basket) or 2 (paddle), and the parallel sampling approach gives very short cycle times for detailed drug release profiles. Integrated System Suitability Tests and video monitoring support reliability, and a 10 batch system needs no more than 2 x 1 m of floor space.
• Disintegration Tester ZT 120 Light (ZT 121 light, ZT 122 light) (Erweka): Erweka position the ZT 120 Light series as the entry level disintegration tester, with one or two motor driven USP / EP / JP compliant test stations. The compact unit carries an integrated flow through heater and a moulded one piece PET water bath with a cover, which Erweka note will not leak or break and is easy to clean. Operation runs from a membrane keypad, where run time and water bath temperature are entered with symbol keys and actual values appear on large bright LED displays. The run time counter starts automatically as soon as the basket rack assembly is lowered into the test media.
• Disintegration Tester ZT 320 Series (ZT 321, ZT 322, ZT 323, ZT 324) (Erweka): On the ZT 320 series the one to four test stations are driven individually, and each station has its own keypad. Once the required run time is programmed, the basket rack assembly with its loaded samples lowers automatically into the media, and on completion of the preset time or when the stop button is pressed the rack is raised out of the media to prevent further disintegration, which is optional. Temperature shown on the LED display is measured by the standard external sensor sitting either in the water bath or in the test media. Recorded test run parameters can be hard copied through the USB printer interface and the actual disintegration time added manually afterwards.
• Disintegration Tester ZT 730 Series (ZT 731, ZT 732) (Erweka): The ZT 730 series determines disintegration time automatically using a cable free AirBasket built around a system of magnets and sensors. It comes with one individually driven test station (ZT 731) or two (ZT 732) and carries an integrated flow through heater. The AirBasket has a sealed electronics compartment, making it dishwasher proof, and durable sensors that allow use in acidic media; it is available as a type A basket with 6 test tubes for standard tablets or a type B basket with 3 test tubes for larger tablets, both to USP / EP / JP standards. Water bath technology uses the thermal inertia of water for a steady test temperature with a PT 100 sensor for constant control, and the 7 inch touchscreen stores and retrieves up to 200 products or methods with their results and parameters.
• Friability Tester TAR II (Erweka): The TAR II is Erweka's upgradeable USP / EP / JP friability and abrasion tester. Its high resolution 7 inch touch display puts the operator's attention on compliant friability testing, with TestAssist automatic calculation guiding the process step by step and an advanced balance connection transferring and calculating data directly. TestAssist offers three testing modes covering revolutions, time and USP test, checking that every parameter is set correctly, and in USP mode it calculates results automatically and triggers repetition of the test where USP guidelines require it. The unit can be configured with one or two test stations plus an optional smart scale, and all of it can be retrofitted later. A stand for the 10 degree position required by USP / EP is included.
• Granulate Flow Tester GT Series (GTL, GT, GTB) (Erweka): Erweka's granulate flow tester family determines the flow behaviour of powders and granules by several measurement methods. The GTL is the entry level device for USP / EP compliant measurement of flowability by weight and by volume, operated through a simple numeric keypad and LC display with printable results. The GT adds a scale so stable weight can be measured during the flow, and on top of the GTL's two methods it measures flowability over a set time and the flow angle with graphical display. The GTB extends the GT with advanced automatic laser measurement of the angle of repose. Accessories such as outlet nozzles of differing diameters, smaller collecting funnels and an optional four stage agitator for poorly flowing samples allow customer specific measurements that are not EP compliant.
• Manual Powder & Granule Density Tester SMG 697 (Erweka): The SMG 697 is a manual powder and granule density tester for reproducible determination of apparent bulk density, usable with all free flowing powders and granulates. Following DIN ISO 697, apparent bulk density is found by measuring the mass of a powder in a container of known size after filling from a funnel of specific shape under defined conditions. Erweka supply the device with operating instructions and a calibration certificate.
• Tapped Density Tester SVM II (Erweka): The SVM II is Erweka's latest generation tapped density tester. Its 7 inch high resolution touch display keeps the operator focused on 100 % USP / EP compliant tapped density testing, and TestAssist automatic calculation walks the user through the process while working out the Hausner Ratio and compressibility index and printing a report after every test. A newly designed SwitchPlate system produces five versions of the instrument, covering USP 1, USP 2 or USP 3 in one or two test station configurations or a combination of both methods, and the user can change from one variant to another within minutes. Supported methods run from USP 1 and USP 2 through to ASTM B527-15 and DIN EN ISO 787-11:1995.
• Vacuum Leak Tester VDT/S (Erweka): The VDT/S tests blisters and other packaging forms for leaks. Maximum vacuum, with an absolute pressure range up to 100 mbar, and the vacuum hold time before release are set from the symbol keypad, while the actual vacuum is shown continuously on the LED display. To check density the instrument runs a methylene blue dye test split into several phases: during pressure maintenance the blisters are exposed to a vacuum generated in the vacuum container, the container is then ventilated, and in the penetration process the blister rests in the methylene blue solution so the solution can be drawn into any imperfectly sealed packaging. Test run parameters such as actual and set vacuum value and hold time are documented through a USB interface or a connected printer, and the integrated vacuum pump can be recalibrated with the optional validation kit containing a type DVR vacuum meter.
• Suppository Penetration Tester PM 30 (Erweka): The PM 30 measures the softening time of suppositories, which must disintegrate, dissolve or melt at body temperature for their active ingredients to be released. Erweka offer a version for EP method A and for method B: the PM 30 penetration tester is Apparatus A according to EP and the PM 3 is Apparatus B. Both were developed to give reproducible measurements of softening time at specified temperatures, and the design of the test device makes visual observation of melting characteristics straightforward. The unit consists of three test stations.
• Suppository Hardness Tester SBT 2 (Erweka): The SBT 2 suppository hardness tester is built around an electrically heated chamber with an integrated sample holder and a set of interchangeable plastic inserts that hold suppositories of different sizes. Once the desired temperature is reached, hardness is tested using weights supplied as standard, which are placed on the device one after another until the suppository collapses under the load. Results are expressed as the total weight required to collapse the suppository.
• Melting Point Tester SSP (Erweka): The SSP measures the melting point of suppository samples. It is made up of a graduated tube with an integrated glass test chamber, and the sample under test sits in a spiral shaped glass test basket inside that chamber. A water jacket surrounds the chamber, and the water within it can be heated with the optional EST 2 circulation heater.
• Suppository Disintegration Tester ST 35 (Erweka): The ST 35 has three turnable test stations, each sitting in a four litre glass vessel with an optional magnetic stirrer, and a thermostatically heated water bath that Erweka describe as leak proof and double secured. Test stations turn automatically through 180 degrees at adjustable intervals. An integrated high performance flow through heating system holds accuracy to ± 0.2 °C and an internal temperature sensor drives the temperature display. Test time and set bath temperature are entered on membrane keys, with current test time and water temperature shown on clearly visible red LEDs, and an alarm can be selected to sound once the set test time has elapsed. The width of the unit lets the test stations be separated for easier cleaning.
• Tablet Hardness Tester TBH 125 (Erweka): The TBH 125 is Erweka's basic device for tablet hardness testing in dual mode, constant speed and constant force, offering accuracy, robust design and quick handling. It is operated through a symbol keypad that makes entering the number of samples straightforward, and up to three physical parameters can be tested: hardness, diameter or length, and thickness. Results including date and time appear on two bright LED displays and can be printed through the standard USB printer interface. Calibration is done either statically with weight stones or dynamically with AutoCal 2.0 using menu guided three point calibration, and the unit produces a calibration print out with individual calibration data, service date and time and serial number.
• Tablet Hardness Tester TBH 325 Series (Erweka): The TBH 325 is Erweka's hardness or combination tester with an integrated product memory for up to 50 products, built robustly for smooth operation in production environments. Its numeric keypad with alphanumeric sub function stores nominal hardness together with three tolerances for each of up to 50 products, ready to be recalled for testing, and product names, remarks and batch or lot numbers can be entered before a test run begins. Recorded information and results can be printed on a connected printer or transferred to a computer through the LAN interface. Samples are inserted manually so all tablet types and shapes can be tested, and broken samples drop from the test station into an acrylic glass disposal container. Hardness is measured from 3 to 500 Newton in constant speed or constant force mode, with measuring sensitivity adjustable from 3 to 40 N.
• Tablet Hardness Tester TBH 425 Series (TBH 425 D, TBH 425 TD, TBH 425 WTD) (Erweka): The TBH 425 is a tablet hardness and combination tester for semi automatic measurement of up to 10 samples. Samples go into a star shaped feeder and are then transported automatically to the test station, where, depending on model, hardness and optionally thickness, diameter or length for oblongs can be measured on round or uneven samples. An alignment routine and an optional support groove in the hardness testing station help align irregularly shaped samples during breaking. The numeric keypad with alphanumeric sub function stores nominal hardness with three individual plus and minus tolerances, where T3 is the pass or fail criterion, plus comments for up to 50 products, and stored product data can be moved to other devices in the TBH 325 / 425 family by SD card or USB stick. Paired with the optional MC.NET software over the serial LAN or USB interface, the series is 100 % 21 CFR 11 compliant.
