Online System Overview
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.
Reliable Operation
With the standard ERWEKA 8-channel peristaltic pump IPC 8 the sample is taken from the dissolution testers via a USP/EP compliant sampling station with stainless steel sampling tubes and is then injected to the flow-through cells of the spectrophotometer. After analysis, the sample is transferred back to the test vessel.
The Disso.net software not only offers a compact analytical report (default report with all relevant data), but also shows method data, calibration data and raw data.
Disso.Net Software – Software for Dissolutions Testers
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).
