Abstract
In a preferred embodiment, a vessel-mouth annulus that precisely fits the inside-diameter of the upper mouth-opening to a water-containable tablet-dissolution stirring vessel, the vessel-mouth annulus being rigidly mounted on an anchoring structure rigidly attached to a paddle-shaft stirring device with one or more of the anchoring arm and/or the paddle-shaft stirring device being mounted in a predetermined fixed position on a base support structure such that a center of the dissolution vessel is centered in exact alignment with a predetermined fixed-position of a downwardly-extending lineally-extending stirrer-paddle shaft on which at-least one stirrer paddle is mounted on a lower end thereof for stirring liquid contained in the dissolution vessel during its operational use, and dissolution vessel support structure positioned to support the dissolution vessel in a state of alignment when the dissolution vessel is pressed upwardly against the aligning guide and holding means in a state of being aligned against inside diameter surfaces of the dissolution vessel. Additionally, rigidly and immovably a part of or mounted on at-least one of the vessel-mouth annulus and/or the anchoring structure and/or the paddle-shaft stirring device, there is included mounting structure for mounting a shaft-centering tester such that continuously or intermittently the revolvable shaft mounting the paddles, may be tested to verify continued exact centered positioning thereof relative to the centered mouth of the dissolution vessel. The tester-mounting structure is adapted to intermittently mount and dismount the the shaft-centering tester.
