BioVortexer and SpiralPestle Grinder
The BioVortexer™ is a battery-powered motor drive designed to rotate stirring rods or our unique SpiralPestles in 1.5 ml microvials. Rotating at thousands of revolutions per minute, it makes short work of dispersing centrifugal pellets or grinding small tissue samples.
Cat. No. 1083MC - BioVortexer Stirring Kit. Includes motor, batteries and 100 - 1/8"X3" stirring rods.
Cat. No. 1083 - BioVortexer, motor only. Batteries included.
Cat. No. 183 - Additional BioVortexer polypropylene stirring rods, 1/8"X3" (500 count).
Cat. No. 1017MC - BioVortexer Grinding Kit. Includes motor, batteries, 100 SpiralPestles™ with matching 1.5 ml microvials and sample of SpiralPestle™ Grinding Beads.
Cat. No. 1017 - Additional SpiralPestles™ with matching 1.5 ml microvials (100 count) and sample of SpiralPestle™ Grinding Beads.
The BioVortexer has two distinct applications...
A practical alternative to a conventional vortex mixer for mixing and dispersing samples. Combined with disposable polypropylene stirring rods, it rapidly re-suspends precipitates such as pellets of protein or DNA. The working range is 10-500 mg of powdered or homogenized solids in a media volume of 0.5 to 10 ml. Take the BioVortexer to the sample instead of the sample to the vortex mixer.
Our SpiralPestle™ grinding pestle is a significant improvement over traditional smooth-walled polypropylene pestle and tube combinations. Featuring a unique screw-like pattern on its surface, the 'threads' of the turning SpiralPestle serve as a screw pump to draw 10 to 100 mg of soft plant or animal tissue suspended in a 200 to 500 µl of extraction solution to the bottom of the microvial where it is macerated and mechanically dispersed between the rounded bottom of the pestle and vial. Tissue grinding is further enhanced by including a pinch of glass grinding beads (a sample is included with each SpiralPestle order).
While pestle and microtube grinders are traditionally operated by hand rotation, optimum homogenization efficiency is acheved by combining the SpiralPestle with the BioVortexer™. With its greatly increased rotational speed (~9000 rpm) and the addition of some glass grinding beads, lysis of soft tissue samples is completed in seconds.
