PERISTALTIC MOVEMENT SIMULATING STIRRING DEVICE FOR DISSOLUTION TESTING

摘要

The present invention relates to peristaltic movement simulating stirring device for dissolution testing and relates to the field of dissolution testing and particular to dissolution testing device which simulates the movement in gastrointestinal tract. A peristaltic movement simulating stirring device for dissolution testing is characterized by a suitable amount of beads added into the stirring vessel (1) comprising a stirring bar (2) and a medium (4) simulating gastrointestinal environment. Beads are added in the amount to achieve the minimum amount which covers the bottom of the vessel in one layer to maximum amount which represents the height of about 400% of the stirring bar diameter. The density of the beads is from 1.1 to 5 g/cm
