A method for the analysis of particles in suspension in a fluid having a conductivity different from that of the particles, in particular a method for the analysis of blood particles is disclosed. The method includes the following steps: passing the fluid through an orifice, applying an electronic signal across the orifice, and producing electronic pulses corresponding to the changes in the signal level caused by the passage of the particles through the orifice. The invention is also concerned with a device for carrying out the method.

Blood particle analyzer

Apparatus for sample transfer and analysis by centrifugation, comprising a rotor having rotary joints at its periphery, to which cuvette carriers are connected so as to be able to perform a tipping movement through an angle of 90.degree., a locking device for locking the cuvette carriers in an inclined position, and cuvette assemblies for use in the cuvette carriers, the rotor preferably being in the form of a rotary beam at the two ends of which two cuvette carriers are disposed, and the cuvette carrier is in the form of a comb so that the teeth engage between the cuvette rows of the cuvette assembly. This apparatus enables samples to be transferred without mixing the cuvette contents.
