PTSW0

Suppository Dissolution Test Apparatus

The PTSWO Suppository Dissolution Test Cell (Rotating Dialysis Cell) is placed into a normal 1 ltr. USP type dissolution vessel which is placed into a Dissolution Test Instrument to test the rate of dissolved active of suppositories and lypophilic carriers. The stirrer drive is coupled by its shaft to the horizontally rotating dialysis cell, which contains the suppository or sample material. Active ingredients diffuse through the cell membrane and can be measured in the normal way by sampling from the outer phase, usually water, where only dissolved active is measured.
The PTSW0 can be used in the following PTA dissolution baths: PTWS - PTWS300/600 - PTWS610 - PTWS1210 - PTWS4000
