    摘要： A method for hemoglobin determination is described which includes the steps of introducing a sample of undiluted whole blood by capillary action into a disposable microcuvette having at least one cavity for receiving the sample. The cavity includes a dry essentially non-hygroscopic hemolysing agent, which is dissolved by the blood, hemolyses the red blood cells and releases the haemoglobin contained in the blood cells. A first absorption measurement at a wavelength range 490-520 nm is then performed directly on the sample in the microcuvette, and a second absorption measurement is performed to compensate for background interference.

    摘要： 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.

    摘要： A cuvette for taking up a fluid and mixing the fluid with a reagent for analyzing the mixture consists of a body (10) of glass or polymeric material having a first cavity (12) in which the fluid can be taken up, preferably by capillary action, through an inlet (13), and at least one further cavity (21) exerting capillary force on fluid which is transported from the first cavity (12) into a reception cavity (17) by subjecting the cuvette to centrifugal force. The further cavity (21) preferably exerts capillary force through a wick (19) which does not extend as far as the bottom of the reception cavity (17), and a capillary channel (20). In those cases where more than one further cavity (21) is provided, each such cavity (21) communicates with a further reception cavity into which the fluid can be transported from the cavity (21) by the exertion of centrifugal force. The cuvette may also have cavities for receiving washing or diluting liquid, which are connected in series or in parallel with the cavity (12).
