A disposable cassette for blood analysis includes a housing having an upper panel and a sampling section having a filling inlet; at least one pair of chambers in a form of depression of the upper panel of the housing and sealed by a diaphragm; portions of the diaphragm over the chambers being flexible; and one or more channels adapted to interconnect the pair of chambers; one of the chambers containing a predetermined amount of a reagent for blood analysis; and a sample outlet disposed next to and connected to the chamber containing the reagent, the sample outlet including an outlet cavity recessed from the upper panel, a divider disposed therein, and a cover covering the outlet cavity; the sample outlet sealing the reagent to the chamber containing the reagent. Further disclosed is the method of using the disposable cassette for measurements of hematology parameters on a blood analyzer.

A miniature flow-through cuvette for spectrophotometric measurement of a liquid sample includes a cuvette body of a transparent material including a first outer surface and an opposing second outer surface, and a flow channel disposed through the cuvette body. The flow channel includes first and second interface segments generally vertically oriented, each having an open exit; a measurement segment interconnecting the first and second interface segments; a first inclined planar inner surface disposed in a turning segment between the first interface segment and the measurement segment, facing the first outer surface; and a second inclined planar inner surface disposed in a turning segment between the second interface segment and the measurement segment, facing the second outer surface. The first and second inclined inner surfaces terminate the measurement segment at opposing ends thereof. Further provided is a spectrophotometer including the miniature flow-through cuvette.
