Dissolution Testers
Online System

ERWEKA offers different types of UV/VIS dissolution testers. First the UV/VIS Online System consisting of a Dissolution Tester from the DT 720 series, a peristaltic pump or piston pump, a spectrophotometer and a connected PC/Software solution for control of the system; and second a UV/VIS On-/Offline System with Dissolution Tester which adds a sample collector FRL to the UV/VIS Online System.

All system components are controlled from a computer via the industry-proven Windows-based Disso.NET software.

Reliable
Operation

With the standard ERWEKA 8-channel peristaltic pump IPC 8 the sample ist 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 ERWEKA SPM double beam 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

The ERWEKA Disso.net software is the perfect 21 CFR Part 11 compliant companion to our dissolution systems. The software offers support of all 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 provides control over each single function and connected device (e.g. dissolution tester or UV/VIS spectrophotometer). Our audit trail generates a detailed protocol recording all events and time. The software includes an easy to handle method editor for highest repeatability. After finishing the dissolution test, Disso.net creates reports with your corporate logo as PDF-file or exports your results (e.g. as XML-file).
