The best laboratory-scale homogenizer for disrupting aqueous suspensions of yeast or bacteria. The BeadBeater comes complete with everything you need with a 350 ml polycarbonate chamber, rotor assembly, motor base, ice-water cooling jacket and one pound of glass beads.
Indicate your glass bead size choice by adding -101, -105 or -110 (which is 0.1, 0.5, or 1.0 mm diameter) to the end of the catalog number (example: 1107900-105). See our Bead link in the Browse box to the left for guidance on selecting bead size. Bead compositions other than glass should be order separately. If you require a european/asian 230 VAC unit, please select a model that ends in -EUR.

The BeadBeater disrupts microorganisms, single-cell preparations and pulverized plant and animal tissue with better than 95 percent efficiency. Up 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 the 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.

CONTROLLING SAMPLE WARMING. Like many mechanical cell disruption techniques, the Beadbeating process generates heat. In general for every minute of beadbeating there is a 10 degree rise in sample temperature. Should that be a problem, the ice-water jacket included with the BeadBeater helps keep this temperature increase under control. Superior control is achieved using an accessory 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 freezer pack gels with a rubber band around the s. s. chamber just before firing up the Beadbeater."
