Abstract
The invention concerns a device for lysis (1) of micro-organism to release at least one intracellular biological constituent, comprising a container (2) wherein are present a biological sample, in liquid medium, containing the micro-organism to be lyzed, and a material in the form of particles, relatively hard and inert with respect to the sample. The invention also concerns a grinding method. The material in the form of particles comprises at least two types of grinding means into different dimensions: at least large dimension magnetic means (3) automatically controlled by a magnetic field; and at least small dimension means (4) actuated by the large dimension grinding means (3). The invention is useful for separating biological constituents.
