  • Thermostated cuvette set
    Patent number: 4824791
    Abstract: The invention concerns a thermostated cuvette set in which samples placed in the cuvettes are measured photometrically. Cuvettes of uniform wall thickness are permanently fixed to the bottom of a basin-shaped frame. The cuvettes are connected by partition walls to each other and to the walls of the basin to form arrays of cuvettes defining a path for flow of the thermostating medium. In a preferred embodiment the path is serpentine. The cuvette set also includes at least one inlet opening and at least one outlet opening in the wall of the basin for circulation of the thermostating medium.
