FIELD: physics.
SUBSTANCE: flow vessel for optical device intended for calculation and/or differentiation of leucocytes comprises vessel case. Besides, it comprises injector arranged almost aligned with vessel case along sample injection axis. Note here that case and injector are aligned along said axis that is perpendicular to optical axis. Also, proposed device comprises appliance to generate flowing shell for sample flow. Note here that sample flow is injected at pressure relative to flowing shell. Note also that said flowing shell acts passively since it does not constrict sample flow width in widening it. Device includes also zone of analysis arranged down stream of injector. Mind that two orifices are arranged along optical axis, one making light beam inlet and the other making outlet of light bean containing data on sample. Note that vessel analysis zone section has, at least, one crosswise size making 1-5 mm.
EFFECT: simple design, higher efficiency and accuracy, chances of process automation.
