Improvements in apparatus for performing an assay to determine the presence or amount of a substance in a test sample, which apparatus comprises means for dispensing one or more reagents from containment means therefor into a reaction vessel and means for dispensing the sample from a sample container into said vessel for reaction with the reagents during performance of the assay, are disclosed. The improvements reside in the apparatus further comprising containment means for the reagents integral and in combination with the sample container and the reaction vessel.

A rotatable carousel for holding disposable containment means, each of which is characterized by a depending cylindrical cuvette holder, said carousel comprising: a plurality of cuvette cavities disposed in a circular pattern around a central axis of rotation thereof; and rotatable locking means disposed co-axially about said central axis and inwardly of said cuvette cavities, said locking means having a plurality of alternating notches and tabs around its periphery, whereby for insertion of a containment means comprising a depending cylindrical cuvette holder into said carousel, said locking means can be rotated so that said notches radially allign with one of said cuvette cavities to allow said containment means to be mounted on said carousel with its cuvette holder received in said one cuvette cavity, and upon so mounting said containment means, said containment means can be locked to said carousel by rotating said locking means so that one of said tabs radially aligns with said one cuvette cavity and overlies a portion of said containment means.
