Like all ERWEKA products, the dissolution online systems are 100% USP / EP / JP compliant

Easy Control of the Complete System

Full system control of all connected components with the Disso.NET software

USP Methods 1, 2, 5 and 6

Use of a variety of attachments for different USP methods due to the standardized shaft design

Proven Erweka Quality Throughout Components

Heart of the Dissolution Online System Dissolution Tester DT 950

The DT 950 is the centerpiece of our online system. It is 100% compliant with USP methods 1, 2, 5 and 6, enabling a wide range of dissolution tests to be performed with our system. It also offers the flexible high-head and low-head modes.

 

Precise Sampling According to USP Sampling Points Automated Sampling Station Ass-9

The automated sampling station ASS-9 is an add-on module for the DT 950. It allows samples to be taken directly from the vessel in accordance with the USP sampling points. These media are then pumped to the UV-Vis spectrophotometer.

 

Efficient & Versatile Pump for Erweka Dissolution Systems IPC 8 Peristaltic Pump or PVP 820 Piston Pump

The IPC 8 peristaltic pump offers an accuracy of +/- 0.5 ml and is the basic pump provided with ERWEKA dissolution systems. The PVP piston pump manufactured by Erweka has virtually maintenance-free ceramic heads and is used for high volumes.
