HYDROFOCUS APPARATUS COMPRISING A SINGLE ANALYSIS SOLUTION

The present invention relates to an apparatus for analysing a blood sample contained in an analysis solution. This apparatus includes a dilution and analysis tray capable of containing the analysis solution. This tray is directly connected to a circulation vessel comprising a sleeve active so that the analysis solution used to measure the haemoglobin content is also used to measure the leukocyte sub-populations of white blood cells, at a predefined dilution rate having a ratio of less than 1/160. The apparatus also includes a hydraulic system which, together with the circulation vessel, is designed to generate a flow of the analysis solution having a diameter of 70 to 90 pm so as to have enough cells for the optical measurement.
