BeadBeater
The BeadBeater comes complete with a 350 ml polycarbonate chamber, rotor assembly, motor base, ice-water cooling jacket (not shown) and one pound of glass beads of your choice.
Indicate your glass bead choice by adding -101, -105 or -110 (0.1, 0.5, or 1.0 mm) to the end of the catalog number (example: 1107900-105). See our Bead Page for guidance in bead selection. Bead compositions other than glass should be order separately. If you need 230 volt unit, please select the models that end in EUR.
Product Description
The BeadBeater disrupts microorganisms and single-cell preparations with better than 95 percent efficiency. One to 80 grams (wet weight) of cells can be processed in a typical three minute run. Relying on a unique crushing or cracking action rather than high shear forces found with a French Press or sonicator, a Teflon impeller rotating at high speed forces thousands of minute glass beads to violently collide in a special clover-leaf shaped vessel. Cells are disrupted quickly, efficiently and safely in the sealed system. The apparatus is easy to clean, has a small footprint, requires no auxiliary supplies or equipment and is essentially maintenance free. Beads settle out in seconds and are reusable.

Other Information
Like many mechanical cell disruption techniques, the Beadbeating process generates heat. In general for every minute of beadbeating there is a 10 deg rise in sample temperature. Should that be a problem, the ice-water jacket included with the BeadBeater helps keep this temperature increase under control. The best control is achieved using a stainless steel or aluminum sample chamber. See accessories below. *Rick Hansen at Solid Tech Animal Health recently suggested another way to keep the sample chamber cold: 'We affix small freeezer pack gels with a rubber band around the s. s. chamber just before firing up the Beadbeater. Seems to work well.'
