Cell disruption can be brought about by a high-speed bead mill, consisting of a series of rotating discs and a charge of glass ballotini (Figure 2).The cell suspension is agitated at a very high speed. The mill chamber is almost full of grinding beads during operation, with the optimum concentration of ballotini usually being 70–90% of the volume of the chamber.
