    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.
