50 ml Tube Holder, Solid Aluminum
This 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 placed completely inside the cold block and the contents shaken in the "wall to wall" direction. The block can be pre-cooled in a deep freezer or, at cryo-temperatures, with dry-ice or liquid nitrogen.
Included with each vial block are 25 sterile, polypropylene 50 ml screw cap tubes (Stockwell brand, part # 3252).*
*Important note: To maximize the efficiency of heat transfer, this aluminum tube holder was designed to fit with close tolerance to the Stockwell-brand 50 ml tube. Other brands of 50 ml centrifuge tube may not fit properly. If you prefer to use a different brand tube, please check with us for compatibility.

An important accessory for the MiniBeadbeater-96 when temperature control is a concern*. Typically, a vial filled with beads, sample and extraction media warms up ~10 degrees per minute of beadbeating. Our 2 ml vial holder (capacity 48 vials) and 50 ml tube holder (capacity 2 tubes) are machined out of high-heat-conductivity aluminum. The vial holders are pre-cooled to low temperatures to provide strict maintainence of low sample temperature during the bead beading process. The cooling efficiency of a close fitting, cold aluminum vial holder is far superior to cold-room air or cold air attachments used by other bead mill cell disruptors.
* Nucleic acid extraction of microorganisms or tissues in the presence of nucleic acid extraction media generally do not require temperature control.
