Research Products International Corp BeadBeater, Small Stainless Steel Chamber, 15 ml Working Volume
Chambers have working volumes (i.e., cells plus buffer) of 15 ml and a maximum sample size of 7g. The chambers are made of stainless steel and polypropylene plastic and can be autoclaved, if desired. The small chambers fit inside the standard 350 ml BeadBeater polycarbonate chamber. The latter may be filled with crushed ice and water and to help keep the sample cold.
BioSpec Products Mini-Beadbeater-96, 115 volt
The MiniBeadbeater-96 disrupts cells and tissue by violently shaking a sample inside a classic 2 ml microvial or standard deep well microplate partially filled with tiny ceramic or steel beads. Complete cell disruption is achieved in 1 to 3 minutes of beadbeating. A common application is nucleic acid extraction. Up to 400 mg of tissue is added to a vial containing glass or ceramic beads and a nucleic acid extraction solution...the later often being purchased as part of a nucleic acid extraction kit. The synergy of simultaneous mechanical cell disruption and nucleic acid extraction in a chaotropic solution gives very high yields of high quality RNA or DNA. Most protocols developed using smaller capacity models of the MBB are transferable with little if any modification.
