Abstract

The present invention is a cuvette provided with at least two cavities. The first or inlet cavity takes up fluid by capillary action. The second cavity is a reception cavity which communicates with the first cavity through a first channel. The second cavity preferably is constructed and arranged to not exert a capillary action, although it could be constructed to exert a capillary action. The first channel which is in fluid communication with the first cavity and the second cavity exerts a non-capillary and non-spontaneous fluid transporting function that is operative only under an external influence, such as by application of a centrifugal force on the cuvette. The cuvette is well suited for a variety of analyses, particularly upon whole blood.
