ball mill method of cell disruption

Cell Disruption - an overview ScienceDirect Topics

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.

Mechanical Disruption Methods: Beating

Most beating methods rely on placing a sample and projectile in a tube and rapidly shaking them back and forth. The most common method is bead beating which uses grinding balls or small beads, though cylinders and irregular shapes have also been used. Bead beating has been in practice for years for the disruption
