SpiralPestle and Tube Grinder
The NEW SpiralPestle™ and 1.5 ml Microtube grinder is an significant improvement over conventional smooth-walled polypropylene pestle and tube combinations. It is used to homogenize culture cells and small samples (<100 mg wet weight) of soft tissue such as liver, brain, and muscle. It is also routinely used to disperse centrifugal pellets, precipitates, and other solids.

HOW IT WORKS: The SpiralPestle™ has a unique screw-like pattern on its surface. Rotation of the SpiralPestle actively draws 10-100 mg of soft plant or animal tissue suspended in a 200 to 500 µl of extraction solution downward to the bottom of a 1.5 ml microvial where it is macerated and mechanically dispersed between the walls of the pestle and vial. Tissue grinding is enhanced by including of a pinch of glass grinding beads (a sample is included with your order).
While pestle and microtube grinders are traditionally operated by hand rotation, to achieve optimum homogenization efficiency the SpiralPestle should be combined with a BioVortexer™. The BioVortexer is a low-cost, hand-held mixing motor drive. With its greatly increased rotational speed and the addition of glass grinding beads, lysis of soft tissue samples is complete in seconds.
