The BeadBlaster™ 24 lyses and homogenizes a broad variety of biological samples.  Many very tough samples can be fully homogenized by the BeadBlaster in under a minute!

The new, refrigerated BeadBlaster™ 24R is capable of refrigeration to -10°C. Unlike most other refrigerated bead mill homogenizers, its on-board refrigeration system operates without the use of dry ice or liquid nitrogen!

The stainless steel tube carrier subjects up to 24 samples to an optimized, high speed, 3D motion, producing high energy impacts between the samples and micro-beads to release cellular contents.  After homogenization, samples can be centrifuged and the supernatant collected for further processing.

Operating parameters for the BeadBlaster 24 are set and displayed digitally. To protect heat sensitive samples, the unit can be programmed to operate in shortened consecutive cycles with a rest period in between to prevent heat buildup.  Up to 50 such programs can be stored in memory and recalled for future use.  A transparent lid allows for visualization of samples, and features a mechanical lid lock that prevents opening when the BeadBlaster is in operation. A brushless motor reduces motor noise and provides maintenance free operation.

Benchmark offers an assortment of pre-filled tube kits for a variety of sample types. The popular Triple-Pure™ kits include acid washed, heat treated, zirconium beads. The beads are tested to be free of nucleases, making them ideal for molecular biology applications. A convenient starter kit is available to accommodate a broad range of sample types and optimize applications.

Can I use normal 2 ml screw-cap tubes in the BeadBlaster 24?

As the tubes for the BeadBlaster are a standard size, you may use any 2 ml, polypropylene, non-skirted, screw-cap tubes with o-ringed caps.


Is there any difference in power between the BeadBug, BeadBug 6, and BeadBlaster 24

Not a lot. The BeadBug 6 and BeadBlaster are about 10% more powerful than the original BeadBug.

The stroke of the BeadBug, BeadBug 6, and BeadBlaster 24 are the same. The BeadBug 6 and BeadBlaster 24 have the same absolute speed range - 4.0 m/s to 7.0 m/s. The speed of the original BeadBug has a slightly narrower range. In RPM (which is what the speed of the BeadBug is given in), the range is 2700 to 4000 RPM. In the BeadBug 6 and BeadBlaster 24, the speed range is 2400 to 4350 RPM.
