Mini-Beadbeater-Plus

Overview

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.

Features:

• Versatile - processes up to 400 mg (wet weight) of bacteria, yeast, algae, tissue culture cells, and plant and animal tissue.
• Simple to operate with intuitive digital controls.
• Two programmable time presets.
• Safety interlock lid design.
• Totally sealed homogenization - no dangerous aerosols.
• Uses disposable 2 ml screw-cap microvials - no sample cross-contamination.
• Proven, near horizontal shaking with a compressed figure-8 (3-D) pattern.
• Powered by a maintenance-free, high torque brushless motor.
• Dual voltage compatibility: 110 or 220 volt.
