<p>In a cuvette (10) for performing a diagnostic test on a specimen, a base (12) defines a first chamber (14) for receiving a reagent, and a second chamber (16) for receiving a test specimen. The base surface (20) defines a frangible wall which is breakable in order to place the first chamber (14) in fluid communication with the second chamber (16). A cover (24) is coupled to the base (12) and includes a self-aligning piercing member (27) having alignment surfaces (30) which slidably contact the side walls (18) of the second chamber (16) upon movement of the cover (24) to the closed position to thereby align the cover with the base (12).</p> |
