Abstract
A dissolution testing machine has a container for a liquid and a holder for pellets, a support for supporting the holder within the container and a drive enabling the holder to be reciprocated via its support so that solvent flushes into and out of the holder. The holder may be a mesh tube, or a solid walled tube, closed at both ends by an apertured member. A set of containers may receive the holder successively, each container containing a solvent of the same or different characteristics.
