[Flow-type cuvette of an optical analyzer with hydrodynamic focusing of the liquid under study]

Described in the paper is a flow cuvette (probe) for an optical analyzer of formed blood elements and other cell suspensions. The cuvette is provided by hydrodynamic focusing of the liquids. The cuvette differs from the commonly known models by the following parameters: a high upper limit of the operating range for the Reynolds number and, as a result, the possibility to increase the analysis rate, high spatial and time resolution, and compactness.
