ABSTRACT:
A cuvet is prepared for test analysis of a substance by placing a predetermined volume of a reagent liquid in a cuvet and then using a pipette or capillary tube for taking up a predetermined volume of the test substance by capillary action. Then the charged capillary tube is placed in the cuvet in the reagent liquid to permit the test substance to flow into the reagent liquid, and the substance is mixed with the reagent liquid in the cuvet so that the substance has a precise and predetermined ratio to the reagent liquid for speedily and accurately preparing the cuvet for a test analysis. A convenient kit is provided, containing a plurality of cuvets already charged with a measured quantity of a reagent liquid, and a plurality of capillary pipettes for use in adding measured quantities of some other liquid (e.g., blood) to the reagent liquid in a cuvet.
