Abstract

A dissolution test apparatus comprises a spindle head assembly interconnected between first and second lateral support members. The lateral support members are translatable along a first axis, and the spindle head assembly is translatable along a second axis, such that the spindle head assembly is movable from a front, operative position at which test procedures are effected, to a rear position at which access to the dissolution test apparatus is enhanced. The spindle head assembly includes a dosage delivery mechanism including an actuatable dosage unit-retaining member. A front portion of the dissolution test apparatus has a tapered width to accommodate a triangular or trapezoidal array of test vessels, resulting in high visibility of the vessels.
