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.
Claims17
A unit for grinding biological samples, comprising:
- at least two tubes with different volumes, said at least two tubes mountable on a support of a grinding device, each tube comprising an internal space having a height (h) along the axis of the corresponding tube and being intended to contain samples to be ground,
- a grinding device including:
- the support for supporting said at least two tubes, the support having an axis, the position of the axis varying by describing a cone, and
- an actuator for driving the support in a precession movement,
- wherein each tube is subjected to a movement (d) defined by a 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,
- wherein the grinding device and the at least two tubes are configured such that, for each tube, the d/h ratio is between 0.55 and 1.
