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