    Tissue grinders disperse and disrupt small tissue samples by being repeatedly pressed or squeezed between two hard surfaces. Usually, one surface is concave-shaped (the mortar) and other convex (the pestle). The mortar can also be shaped to the geometry of the test-tube, in which case the pestle is tight fitting with a clearance of 0.1 - 0.2 mm between the inner walls of the test tube and the ...

  • INTRODUCTION GUIDELINES

    Sample variability Different samples vary in their resiliency to homogenization by bead beating. Even moderately resilient samples can be effectively homogenized using an apparatus such as the Geno/Grinder and MiniG. An effective approach to homogenization is to find a balance between sample mass, vessel volume and grinding media material and size.
