Dissolution On-/Offline System UV/VIS

Dissolution On-/Offline System UV/VIS


Semi-automated dissolution system with connected UV/VIS measurement and sample collection, controlled by Disso.NET

The ERWEKA dissolution UV/VIS On-/Offline system is the ideal system configuration for spectrophotometers. With the connected PC, the On-/Offline system can be conveniently controlled via our advanced Disso.NET software. Moreover, the software offers full control over all components.

After analysis has been completed, the samples are comfortably stored by our very own sample collector FRL 624/724/824.



The ERWEKA Disso.NET software is the perfect 21 CFR Part 11 compliant companion to our dissolution systems. The software provides support for all test methods manageable with the ERWEKA DT dissolution testers as well as the automated RoboDis II.

Disso.NET helps you with standard dissolution jobs, handles qualifying tasks and offers control over each single function of the connected devices (e. g. dissolution tester, UV/VIS spectrophotometer or HPLC analysis unit). Our audit trail generates detailed protocols of all events and times. The software additionally includes an easy-to-use editor for comfortable programming of the dissolution methods (for highest repeatability). After finishing the dissolution test, Disso.NET generates comprehensive reports (as PDF-files) with your corporate logo and/or exports the results (e. g. in XML format).
