    摘要： A multicuvette rotor for use in a centrifugal analyzer defines a circumferential array of elongated radially extending cuvettes. The rotor includes a one-piece body member of material that is transparent at analytical wavelengths and has a planar upper surface and defines a circumferential array of elongated cuvette recesses, and a one-piece cover member of similarly transparent material that has a planar lower surface parallel to the planar upper surface of the body member. A continuous seal extends 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 with a loading port in the cover member through which the first constituent is introduced into the first chamber region, a second chamber region for receiving a second constituent with a loading port in the cover member through which the second constituent is introduced into the second chamber region, divider structure between the first and second chamber regions provides a transfer passage between the first and second chamber regions through 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. Extending along the top of each sidewall of each cuvette between the loading ports of the first and second chamber regions is barrier structure that fills the junction between the cover and body members so that there is no capillary channel at that junction and premature mixing of the constituents due to wicking movement of a constituent stored in one of the chamber regions to the other chamber region along that junction is inhibited.

    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.
