ABSTRACT:
A cuvette for use with automatic chemical testing apparatus of the type used for making absorbance measurements of blood serum to which reagents are added to cause chemical changes. The cuvette is disposable, is molded from clear plastic resin as an integral member, has a lower vertically arranged elongate body and an upper funnel-like head portion. The head portion enables positioning of the cuvette in the apparatus where used and the lower portion provides a pair of opposing planar walls through which a beam of radiant energy may be projected and relatively arcuate connecting walls to enable the mixing of the liquids within the cuvette. The configuration enables very little sample to be used in making a test.
