The Dispersion Releaser is connected to the dissolution tester by a special coupling directly affiliated to the stirrer shaft. This way the Dispersion Releaser can be hooked to the coupling and as well easily removed from the stirrer shaft for preparation and cleaning purposes. This ensures a direct transfer of the stirring movements to the stirrer of the Dispersion Releaser.
Basically the Dispersion Releaser consists of a donor and acceptor compartment. The donor compartment is a cylindrically construction which contains the substance to be tested. This construction is surrounded by a membrane, fixed through two O-rings, which acts as barrier between donor and acceptor compartment.
In the inside of the donor compartment is a small paddle, with integrated magnets, directly influenced and controlled by the stirrer shaft of the dissolution tester. Through the integrated magnets an external magnetic stirrer, located at the bottom of the donor, is driven to mix the media in the acceptor compartment.
