BioSpec Products • Tissue Grinders

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.
