BioSpec Products • Bead Mill Cell Disrupters

Bead Milling (Beadbeating) is the preferred laboratory method for disruption of cells to recover intracellular proteins, nucleic acids and organelles. It's fast, efficient, and safe. First to introduce this method of cell disruption to the R&D laboratory in 1979, BioSpec Products now produces five different models of beadbeaters.

Bead Mills - SolidsWiki

Typically, a higher volume ratio of beads to cells produces a faster rate of cell disruption. After the processing cycle is complete, the beads settle by gravity in the vessel and the resulting homogenate is easily removed by pipette. Bead Mills are relatively cross-contamination free because of the disposable beads and sample tubes they employ.
