Products

• PV Factory inspections China, India and South-East Asia — EternalSun: An inspection service for PV plant owners, project owners, EPCs, installers and wholesalers buying modules in Asia. A local team can audit the factory, supervise production, arrange third party laboratory testing and run pre shipment checks for microcracks and soldering faults.
• On site service and simulator calibration — EternalSun: Field service, maintenance and calibration for installed Eternal Sun and Spire solar simulators. Trained engineers give on site support, calibration and troubleshooting, and new and repaired parts ship from several locations to limit equipment downtime.
• Riso GM-25-5A Low-level beta GM multicounter — Riso: A low level gas flow Geiger Muller multicounter that measures five samples at the same time. A common guard counter cuts the cosmic ray background by anticoincidence, and the unit is normally placed inside a 100 mm lead shield for environmental radioactivity work.
• Nanoscale Device Characteristics Analysis System Nano-Prober NP8000 — Hitachi High-Tech: The NP8000 Nano-Prober is a SEM based probing system for electrical characterisation of devices at 5 nm nodes and beyond. It supports electron beam absorbed current imaging, pulsed IV measurement and a temperature controlled stage inside the vacuum chamber.
• FIB Micro-sampling System — Hitachi High-Tech: The Micro-sampling System extracts a small pillar of material from a chosen point on a wafer using the ion beam inside the vacuum chamber of a FIB system. The extracted sample is then trimmed and transferred for analysis by TEM or STEM.
• Ion Milling System ArBlade 5000 — Hitachi High-Tech: The ArBlade 5000 is a broad argon ion beam milling system that prepares cross sections and flat milled surfaces for electron microscopy. Intermittent beam irradiation and a swinging stage produce clean faces across a wide range of materials.
• Ion Milling System IM4000II — Hitachi High-Tech: The IM4000II is an argon ion milling system that carries out both cross section milling and flat milling in one instrument. Options for cooled temperature control and an air protection holder allow preparation of heat sensitive and air sensitive specimens.
• MC1000 Ion Sputter Coater — Hitachi High-Tech: The MC1000 is a magnetron ion sputter coater that deposits a thin conductive metal layer on samples before SEM observation. Platinum, gold and their palladium alloys can be applied, with the coating thickness set from the touch screen control.
• Sample Cleaner ZONESEMII — Hitachi High-Tech: The ZONESEMII is a benchtop sample cleaner that removes hydrocarbon contamination from SEM specimens and holders using vacuum controlled UV irradiation and activated oxygen. It also acts as a vacuum store to prevent holder outgassing.
• Sample Cleaner ZONETEM II — Hitachi High-Tech: The ZONETEM II is a desktop sample cleaner for TEM specimens. It uses vacuum controlled UV irradiation to remove hydrocarbon contamination from the sample surface before imaging, without the use of chemicals, supply gases or reagents.
• Posi3 USB — Honeywell: Computerised NFPA compliant breathing machine that tests self contained breathing apparatus, checking facepiece integrity, regulator performance, pressure accuracy, alarms and breathing resistance. It connects to a Windows PC by USB and stores results automatically.
• 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.

• 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.
• Manual 5-Parameter Hardness Tester TBH II — Erweka: The TBH II covers manual 5 parameter tablet hardness testing in one compact instrument, built for pharmaceutical quality control and research laboratories.
