FIELD: physics; measurement.
SUBSTANCE: invention refers to materials research or analysis using optical facilities and can be used for experimental analysis of blood and its components (cells). Tester contains optically transparent cell with magnetic stirrer mounted in thermostating unit, laser module illuminating the cell, and gauging unit recording light scattering intensity with at least one scattered optical radiation detector. Optical axis of laser module and normal line to sensitive land of optical radiation detector make minimum angle, sufficient to prevent optical radiant flux passing through the sample cell from light-sensitive land of detector.
EFFECT: improved sensitivity and reliability of testing.
