摘要： 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.

摘要： A multicuvette rotor for use in a centrifugal analyzer includes a one piece body member of molded transparent material that defines a circumferential array of elongated cuvette recesses and a one piece cover member of molded transparent material, the cover and body member being bonded together to define a circumferential array of individually sealed separate analytical cuvettes. An annular recess in the cover member adjacent the periphery thereof has a planar optical finish base surface. Located inwardly of the annular recess in the cover member are first and second sets of circumferential arrays of loading ports so that each elongated cuvette defines a first chamber for receiving a first constituent introduced through a loading port of the first set, a second chamber region for storing a second constituent introduced through a loading port of the second set, divider structure between the first and second chamber regions that separates the two chamber regions and that has a crest portion that defines a transfer passage between the two chamber regions, and an analysis region adjacent the periphery of the cuvette where the reaction product formed by a mixture of the first and second constituents may be subjected to analysis. Structure in the base of each analytical region defines an optical window aligned with a corresponding portion of the annular recess in the cover such that an optical path for a beam of analysis radiation through the analysis region is defined.

摘要： An improved analytical cuvette assembly includes structure defining a first chamber region that has a loading port through which a first reaction component is introduced for storage, structure defining a second chamber region having a loading port through which a second reaction component is introduced for storage, and barrier structure between the first and second chamber regions that has a crest portion that defines the lower edge of a transfer passage between the two chamber regions. The second chamber region includes an analysis region where the reaction product resulting from mixture of the two reaction components is subjected to analysis. Each chamber region is defined by opposed planar side wall surfaces and a planar base wall surface, and capillary flow inhibiting structure extends from the crest of the barrier structure along the intersection between a planar surface portion of the barrier structure and the side wall surface and along at least a portion of the intersection of the side wall surfaces and the base surface.
