ABSTRACT:
A cuvette for holding a liquid specimen during centrifugal testing and analysis of the specimen by a spectrophotometer. The cuvette includes a hollow main body produced from a transparent material to allow analysis of the specimen within the cuvette. Two bags of reagent are mounted within the cuvette main body and are designed to burst upon attainment of a given level of centrifugal force allowing the reagent to flow from the bags into a mixing chamber within the cuvette main body. A plug is sealingly mounted to the lid of the cuvette and is removable to allow insertion of the liquid specimen into the cuvette prior to centrifugal testing. Projections are provided on the cuvette to control the orientation of the cuvette when inserted into a diluter test receptacle. One projection on the cuvette contacts appropriate switch means within the test receptacle in turn operable to activate means for diluting the specimen prior to insertion into the cuvette. A container of desiccant is mounted within the cuvette and is operable to absorb vapors. Means are provided to hold the bags of reagent within the cuvette during centrifugal testing.
