The Mini-BeadBeater-16 disrupts microbial cells and plant and animal tissue by violently agitating four to sixteen 2 ml screw-cap microvials containing small glass, ceramic or steel beads and disruption buffer. Even resistant samples like yeast, spores or fibrous tissue are completely homogenized around 3 minutes in 0.1 to 1 ml of extraction medium. The non-foaming, aerosol-free method preserves enzymes and organelles. In the presence of nucleic acid extraction media such as phenol, Gu-SCN or a commercial kit solution, DNA and RNA are recovered in the highest possible yield. The method is ideal for PAGE, PCR applications and diagnostics using antibody or oligonucleotide probes. Because beads and vials are disposable, there are no cross-contamination concerns when homogenizing multiple samples.SKU: n/a
The new Mini-BeadBeater-Plus™ is a high-energy bead-mill designed to violently agitate up to a half gram sample of biological material sealed inside a 2 ml microcentrifuge vial containing tiny glass, zirconia or steel lysing beads. The grinding action of the beads (beadbeating) rapidly disrupts microorganisms and plant and animal tissue in 5-90 seconds. Being an upgrade of the venerable MiniBeadbeater-1, new features include a programmable timer, a more powerful brushless motor and 115/230 VAC compatibility.
Because cell disruption occurs inside sealed microvials, cross-contamination during homogenization is completely eliminated – an important feature for nucleic acid isolation. And time is saved because no clean-up is needed between samples. Sterile technique is easily accommodated for recovery of intracellular virus and bacteria from plant and animal cells and the non-foaming, non-aerosol method is ideal for recovery of enzymes, membranes and intracellular organelles.
The Mini-BeadBeater-Plus is also used for dry- or cryo-grinding. Heavier zirconia or steel beads and special breakage-resistant microvials are used. Hard samples such as hair, bone, teeth, seeds, and minerals are powdered in 5 – 30 seconds. All protocols developed with the Mini-BeadBeater-Plus are transferable to larger, higher-capacity MiniBeadBeater models.SKU: n/a
