The BeadBeater™ is a unique but simply designed apparatus. A solid Teflon® impeller rotating at high speed forces thousands of minute glass beads to collide in a specially shaped vessel. Cells are disrupted quickly, efficiently and safely. Being a totally sealed system, no air is introduced into the preparation - no irritating or toxic aerosols are formed. One can get better than 90% cell disruption in less than 3 minutes. The apparatus is easy to operate, requires no auxiliary supplies or equipment and is essentially maintenance free. The beads settle out in seconds and can be re-used.

  • When working with Bacteria use the 0.1mm diameter beads.
  • When working with Yeast/Fungi use the 0.5mm diameter beads.
  • When working with Most Tissue use the 1.0mm diameter beads.
  • When working with skin or plant material use the 2.5mm beads.
  • When working with tough samples use the same size beads (as above) but chose a more dense material. For example, most researchers prefer 0.1mm zirconia-silica beads for disruption of spores or 2.5 mm zirconia beads or stainless steel beads for extraction of fibrous plant material.
  • Glass Beads have a density of 2.5 g/cc (most commonly used wet grinding media for biopreps)
  • Zirconia/Silica Beads have a density of 3.7g/cc (50% more dense than glass
  • Good for spores and many tissues)
  • Zirconia Beads have a density of 5.5g/cc (100% more dense than glass - good for tough tissue)
  • Stainless Steel Beads have a density of 7.9g/cc (used mostly for dry grinding of leaves)
  • Tungsten Carbide Beads have a density of 14.9g/cc (not recommended for biopreps - leaves prep dirty)
