ABSTRACT:
A plastic assay cuvette having the desired optical properties for the analysis of a test sample or reaction mixture thereof, and a method for making such plastic assay cuvette, are described. The optical properties of the plastic assay cuvette are substantially the same as the optical properties of glass wherein low birefringence throughout the optical read region thereof is provided. When used for the analysis of a test sample or reaction mixture thereof, such as in fluorescence polarization assays and absorbance assays, the plastic assay cuvette provides accurate and reproducible results while, at the same time, provides a low-cost disposable assay cuvette which can be used in place of conventional glass assay cuvettes.
