Abstract
An improved analytical cuvette rotor assembly for use in a centrifugal chemistry analyzer comprising a disc-shaped body having a plurality of radially extending compartments for retaining fluids. Sample fluids and reagent fluids contained in the compartments prior to centrifugation are separated by a novel dam structure extending between upper and lower surfaces of each compartment such that the premature mixing of sample and reagent fluid is significantly retarded. The dam, in cooperation with the compartment walls, further defines a fluid transfer passage that permits fluids to be transferred over the dam under analyzer operating rotational speeds.
