  • Tools for Bead Beating OPS Diagnostics LLC

    Tools for Bead Beating. A simple and well established method for disrupting samples is by bead beating which uses grinding balls and a shaking homogenizer, or mixer mill, to smash, rip, and tear samples. Bead beating can be done in microfuge tubes to disrupt bacteria or in larger vessels to homogenize full organs.

  • Cell Disruption: Sonication vs. Homogenization

    Dec 17, 2015· Beadbased homogenization uses plastic or metal beads combined with highspeed shaking to create shearing forces. This technique is wellsuited to whole animal, insect (, Drosophila melanogaster) or plant specimens, which requires disruption of sturdy cell walls. A drawback of beadbased disruption is that it requires the proper selection of bead material and diameter.
