ERWEKA SVM II Tapped Density Tester
The SVM II is the latest generation of tapped density testers from ERWEKA. With unprecedented flexibility and intelligent features, it makes tapped density testing easy and reliable. The 7“ high resolution touch display with modern interface focuses the user on the most important task tapped density testers have to fulfil – 100% USP/EP compliant tapped density testing. With the automatic calculation features of the Test Assist, the user is guided step-by-step through the testing process as quickly as possible. It also automatically calculates the Hausner Ratio and compressibility index and prints the reports after every test. In addition to its ease of use, the SVM II is the most flexible tapped density tester we have ever sold. The intelligent Switch Plate system enables 5 different versions of the SVM II, with both USP 1 and USP 2 in either one or two test station configurations or a combination of both methods. And the best part – they can also be upgraded at a later date! The SVM II also supports a variety of method and norms: From USP 1 and USP 2 to ASTM B527-15 and DIN EN ISO 787-11:1995 – with the SVM II, users are on the safe side of valid and conforming tapped density testing.

ERWEKA DT 9510
The ERWEKA DT 9510 range of dissolution testers are the bigger sibling of the digital DT 950 series. Controlled by the same embedded PC, every component of the DT 9510 is focused on reliable, high volume digital dissolution testing: The test stations (up to 14) are driven by a single, powerful motor and the big water bath holds the temperature stable due to the thermal inertia of water. This ensures that parallel testing of two batches of samples can be done at precisely the same conditions, making comparison between the two as reliable as possible and 100% USP/EP compliant. With the new optional AirLift system, the dissolution head of the DT 9510 can be simply raised and lowered by the press of two buttons. Furthermore, DT 9510 dissolution testers have the same features as it‘s smaller sibling, with digital dissolution testing is done with the help of the latest version of the testing assistant – TestAssist and optional automatic tablet drop.

ERWEKA Offline Dissolution System
The Digital Offline System for the DT 950 and 9510 series is the next step in harnessing the power of digital dissolution testing. It extends the advanced technology of the DT 950 and 9510 series with the first step in dissolution automation: fully automated sampling and storage in vials for separate analysis. With the updated TestAssist, the user can easily configure and start dissolution tests with automatic sampling on our 7-inch touch display. The design principles introduced with the DT 950 have been applied to offline testing, making it faster, easier and more accurate than ever before. The user is guided through the dissolution test with automatic sampling in a few simple steps. This enables 100% USP / EP / JP compliant dissolution testing without distraction or error and ensures consistently compliant parameters. But it doesn't stop there - with user management, conformant handling of the complete Digital Offline system is just the touch of a button away. Users can be easily configured with individual rights, making it easy to restrict functions to authorized users only - such as administrators, operators and service technicians. The ERWEKA DT 950 / DT 9510 is developed to meet the requirements for compliance and data management for modern laboratories. Its integrated Audit Trail records all user and system actions in detail, including user, time stamp, event, reason for changes, and parameter modifications with old and new values, ensuring complete traceability. Method Management & Approval allows authorized users to create, edit, and approve methods, while User Management provides secure access control with tailored permissions. The Backup & Restore function enables all important data—including methods, user profiles, reports, settings, and audit entries—to be backed up and restored via USB stick, with every event logged for transparency.

ERWEKA Online Dissolution System
ERWEKA dissolution testers with online systems are the perfect, semi-automatic solutions for dissolution testing with automated UV/VIS online analyses. The DT 950 with the integrated, automated ASS-9 sampling station transports freshly sampled media directly to the UV/VIS analysis device (several brands available). There, the samples can be measured and the results stored within our advanced Disso.NET dissolution software. ERWEKA offers different types of UV/VIS analysis devices, such as the Shimadzu 1900i, the Analytic Jena Specord 210/8 or the Agilent Cary 8454. All combined with our dissolution tester DT 950 and a peristaltic pump IPC 8 and all controlled by the Disso.NET PC software.

ERWEKA Friability Tester
ERWEKA TAR friability testers are USP/ Pharm.Eur./ JP compliant ERWEKA units for testing friability and/or abrasion. The high resolution touch display with a modern user interface focuses the user on the most important task the new TAR II has to fulfil – 100% USP/EP compliant friability testing. The friability tester rotation speed can be programmed between 20 and 100 rpm and test run duration can be set in either time or total number of revolutions. During the test run the actual rotation speed and the test run duration is shown on the display. For larger samples the friability tester can be set to the USP / Pharm.Eur. required 10° position by a standard switching leg. To increase the ease of handling on the friability tester, the friability drums don’t have to be removed and opened for loading and emptying. Instead the friability drums are loaded through an opening. On completion of the test run, the samples are automatically removed into a container located under the drum. The new, optional direct balance connection offers seamless integration of supported balance into TestAssist. When setting up a test with TestAssist and a connected balance, TestAssist prompts the user to place the samples on the balance. It then receives the balance data fully automatically, using it for its fully automated calculation. The TAR can be configured with 1 or 2 test stations – but it can also be upgraded from 1 to 2 afterwards. The optional, intelligent balance feature can also be upgraded further down the line.
