ABSTRACT:
An apparatus is disclosed for counting and determining at least one leucocytic sub-population, comprising a case for injecting a flow of sample to be analyzed inside a measurement tank through which a light beam passes, comprising internal and external nozzles for sleeving the sample by means of a pressurized liquid. Electrodes for the resistivity measurements of the leucocytic sub-population are component elements of the injection case. Units for collecting and processing the signals delivered by the optical sensor and the electrodes are also provided.
