Disruption using bead mills. In disruption using a bead mill, the sample is agitated at high speed in the presence of beads. Disruption occurs by the shearing and crushing action of the beads as they collide with the cells. Disruption efficiency is influenced by: Size and composition of beads ; Ratio of buffer to beads ; Amount of starting material
