PTSW-0

Suppository Dissolution Test Cell (Rotating Dialysis Cell)

The PTSW-0 Suppository Dissolution Test Cell (Rotating Dialysis Cell) is placed into a standard USP type dissolution vessel which in turn is inserted into a standard tablet dissolution testing instrument to test the rate of dissolved active of suppositories and lipophilic carriers.

Design

The cell is immersed in the dissolution vessel. It is developed for the study of drug release from hydrophobic carrier preparations, such as suppositories. It encloses a small volume (max. 30ml) of inner fluid by means of a dialysis membrane. The cell itself rotates horizontally in a larger volume of test medium, which has the same pH as the inner volume. The sample is placed inside the inner cell. The rotating speed is reduced in by a factor of 4:1 using a gear. The active dissolves through the membrane into the outer phase and can be measured there using common detection technology like UV/VIS spectrocopy for example. It is proven that the PTSW-0 cell is a suitable tool to study factors which may influence the dissolution and absorption of controlled release formulations.
