ABSTRACT:
A multicuvette rotor for use in a centrifugal analyzer defines a circumferential array of elongated radially extending cuvettes and includes a one-piece body member of molded transparent material that has a planar upper surface and that defines a circumferential array of elongated cuvette recesses, and a one-piece cover member of molded transparent material that has a planar lower surface parallel to the planar upper surface of the body member with a continuous seal extending around each cuvette recess between the planar upper and lower surfaces to define the circumferential array of analytical cuvettes. Each elongated cuvette defines a first chamber for receiving a first constituent, a second chamber region for receiving a second constituent, divider structure between the first and second chamber regions over which the first constituent may be flowed into the second chamber region for forming a reaction product with the second constituent, and structure defining an analysis region adjacent the radially outer wall of the cuvette where the resulting reaction product is subjected to analysis. Barrier structure integral with the cover member extends along the surface of the cover member from the seal and inhibits premature mixing of the constituents due to wicking movement along the cover member of a constituent stored in one of the chamber regions to the other chamber region.
