Products

• Dissolution Tester Software Disso.NET 4: 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: 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: 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.
• Digital Dissolution Tester DT 950 Series (DT 956, DT 957, DT 958): 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 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): 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): 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'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: 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): 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: 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'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: 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'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 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 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): 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): 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: 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'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: 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: 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: 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: 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: 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: 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: 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: 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: 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): 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: The TBH II covers manual 5 parameter tablet hardness testing in one compact instrument, built for pharmaceutical quality control and research laboratories. It measures hardness up to 500 N, thickness, width for oblongs, diameter for round tablets or length for oblongs, and weight, giving pharmacopoeia compliant tablet testing across all five properties. A top mounted touch interface guides the operator through each test step with TestAssist, supported by robust mechanics and an ergonomic, space saving design. Four interchangeable magnetic inserts, flat and with 1, 2 or 3 mm groove radius, position and align tablets from 1 to 30 mm as standard, with an optional user changeable breaking jaw for larger tablets from 31 to 60 mm.
• Tablet Hardness Tester EasyCheck: EasyCheck is a compact, fully automated entry level combination tester for routine tablet hardness work. It measures up to five parameters in a single workflow, weighing samples automatically through its integrated weighing cell so no manual handling is needed. The patented Oblong Slider aligns tablets precisely for consistent results across different tablet shapes, and a star shaped rotary magazine in stainless steel and aluminium provides 20 test positions while leaving the test process fully visible. An intuitive touchscreen stores up to 100 products, methods and users, and the instrument can be fitted with a test memory for up to 1 million test results, an audit trail light function for paperless reporting and CSV and XML data export.
• Tablet Hardness Tester MultiCheck 6: MultiCheck 6 is a fully automatic combination tester built for ease of operation, maximum efficiency and operator convenience. Among its features are an intuitive touch display carrying integrated MC.NET software functionality, a capsule weight measuring system and a patented Oblong Navigator, and Erweka claim an unsurpassed low noise level and the cleanest operation in its class. The empty capsule weight measuring system determines capsule weight and deducts it automatically from the weight of filled capsules, with direct ejection immediately after weight measurement to speed the process up. Proven features are retained: the instrument tests up to five tablet parameters, is fully automated and 100 % compliant with all pharmacopoeias worldwide. It stores 100 products and methods as standard and holds up to 1 million test results.
