Abstract

An apparatus for use with a dissolution testing device comprising a vessel and a shaft with a stir element affixed to one end thereof for placement within the vessel. In one embodiment, the apparatus has a front portion having a first jaw portion and a back portion having a second jaw portion. The front portion is slidably coupled to the front portion, and the first and second jaw portions form a jaw interposable between the bottom of the stir element and the inside bottom of the vessel. The jaw has a jaw distance corresponding to the position of the front portion relative to the back portion. The apparatus also includes a shaft alignment portion for aligning the apparatus parallel to the shaft, and a measurement portion for providing a distance reading corresponding to the gauge jaw distance.
