Bead Milling Method Of Cell Disruption Industry

Now let’s talk about the Bead Milling method of cell disruption. The Bead Mill is a common equipment for breaking microbial cells. Generally, there are two types of vertical and horizontal. However, the horizontal type is superior to the vertical type in terms of efficiency and productivity.

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.
