50 ml Tube Holder, Solid Aluminum
The tube holder is machined out of a 1.5 lb aluminum block and has the dimensions of a standard 2ml deep well microplate. It is used with the MiniBeadbeater-96 cell disrupter. One or two 50 ml screw cap centrifuge tubes are positioned completely inside the cold block. The contents are shaken in a "tube wall to tube wall" direction. The block can be pre-cooled in a deep freezer, or to cryo-temperatures with dry-ice or liquid nitrogen.
Included with each vial block are 25 sterile, polypropylene 50 ml screw-cap tubes.*
An important accessory for the MiniBeadbeater-96 when temperature control is a concern.* Typically, a vial filled with beads, sample, and extraction media will warm ~10 degrees per minute of beadbeating. Our 2 ml vial holder (capacity of 48 vials) and 50 ml tube holder (capacity of 2 tubes) are machined out of heat-conductive aluminum. The vial holders can be pre-cooled to low temperatures to provide maintenance of low sample temperatures during the bead beating process. The vial cooling efficiency of this close-fitting aluminum vial holder is far superior to cold-room air or cold-air attachments used by other bead mill cell disruptors.
* F.Y.I. Nucleic acid extraction of microorganisms or tissues in the presence of nucleic acid extraction media generally does not require temperature control.
