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.

Once liquid nitrogen has completely evaporated, cap with a new lid and store the cell pellet in a −80°C freezer.

Bead beater cell lysis compared to rotor stator homogenizers

False. Mechanical homogenizers are more than capable of providing the same level of cell lysis in a fraction of the time it takes a bead mill. Most mechanical homogenizing is done in a matter of seconds with ZERO heat produced and you can continue on with your same tubes you are processing in, no need to buy special tubes and beads!

Ball mill - Wikipedia

A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
