Abstract
An improved analytical cuvette assembly includes structure defining a first chamber region that has a loading port through which a first reaction component is introduced for storage, structure defining a second chamber region having a loading port through which a second reaction component is introduced for storage, and barrier structure between the first and second chamber regions that has a crest portion that defines the lower edge of a transfer passage between the two chamber regions. The second chamber region includes an analysis region where the reaction product resulting from mixture of the two reaction components is subjected to analysis. Each chamber region is defined by opposed planar side wall surfaces and a planar base wall surface, and capillary flow inhibiting structure extends from the crest of the barrier structure along the intersection between a planar surface portion of the barrier structure and the side wall surface and along at least a portion of the intersection of the side wall surfaces and the base surface.
