Abstract
In a biological sample grinding device and method, a bearing having a plurality of rolling elements disposed between a pair of rings is disposed in a container in which a fluid having at least one biological sample particle therein is introduced. With the bearing immersed in the fluid having the biological sample particle therein, one ring of the bearing is rotated relative to the other ring thereof, whereupon the rolling elements roll between the pair of rings and, in response thereto, the biological sample particle is drawn by the fluid between the pair of rings where it is subject to being crushed or ground between at least one of the rolling elements and at least one of the rings. A baffle can be disposed in the container for inhibiting the rotation of the fluid and, hence, the introduction of air into the fluid.
