Abstract
A dissolution testing apparatus includes a base structure, a vessel support structure, a cleaning manifold and a stirring mechanism. The vessel support structure is configured for mounting testing vessels and is rotatably mounted to the base structure. The vessel support structure is rotatable from an upright position at which respective open ends of the vessels face upwardly to an inverted position at which the open ends face downwardly. The cleaning manifold is mounted to base structure below the vessel support structure and is configured for directing a fluid into the vessels while the vessel support structure is at the inverted position. The stirring mechanism includes shafts and is movably mounted to the base structure. The stirring mechanism is movable from a lower position at which the shafts extend into the vessels to an upper position at which the shafts are outside the vessels. At the upper position the stirring mechanism provides clearance for the vessel support structure to rotate.
