  • Unit for grinding biological samples
    Patent number: 10677692
    Abstract: A unit for grinding biological samples, comprising a grinding device including at least two tubes having different volumes, suitable for being mounted on a support of the grinding device, each tube comprising an inner space having a height (h) along the axis of the corresponding tube, and being intended to contain samples to be ground, means for driving the support in a precession movement, the support having an axis the position of which varies by describing a cone, each tube being subjected to a movement (d) defined by the projection, onto the axis of said cone, of the distance between the extreme positions of a same point of the tube during the precession movement.
    Type: Grant

  • Apparatus for grinding biological samples
    Patent number: 7954741
    Abstract: Apparatus for grinding biological samples contained in tubes (12) carried by a turntable (10) driven with oscillating motion, the zone in which the tubes (12) oscillate being surrounded by cooling means (30) enabling the samples in the tubes (12) to be maintained at a desired low temperature, e.g. 4° C., while they are being ground.
