Abstract
A disposable cuvette cartridge for optical measurements is formed from three flexible thin layers. The middle layer is an adhesive sheet with cut out regions, typically between 30 and 50, serving as optical chambers bounded by the two outer layers. Inlet and vent holes in one of the outer sheets provide access to the optical chambers. At least one of the outer sheets is made of a material having low fluorescence, such as a cyclo-olefin copolymer. With its low background fluorescence, the cuvette cartridge is useful for high-throughput fluorescence measurements of biological samples.
