The PT-SWO Suppository Dissolution Test Cell (Rotating Dialysis Cell) is placed into a normal 1 ltr. USP type dissolution bath 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. 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 PT-SW0 can be used in the following PTA dissolution baths: PTWS - PTWS 300/600 - PTWS 610 - PTWS 1210 - PTWS 4000
