Vial Rack, Solid Alumimum, for 2 ml Microvials
This solid aluminum vial rack for 2ml vials offers superior temperature control during beadbeating than bead mill cell disrupters relying on flowing air chilled by dry-ice or refrigeration. It is well-known that chilled air has much poorer heat conductivity than chilled metal. The block is pre-cooled in a deep freezer or, to cryo-temperatures with dry-ice or liquid nitrogen. Having dimensions of a standard deep-well microplate, it is compatible with not only our MiniBeadbeater-96 but with several competitor microplate shakers.

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) is machined out of high-heat-conductivity aluminum.
The vial holder is pre-cooled to low temperatures inside a refrigerator, a -80º C freezer, or with liquid nitrogen. During the beadbeating process, the chilled vial holder keeps the sample temperature at desired low temperatures.
A related application is 'dry' bead-grinding of fresh tissue by the cryopulverization technique. The sample, beads, vials, and vial holder are all pre-chilled to liquid nitrogen temperatures before being processed in a Mini-BeadBeater-96.
** Helpful Note: Nucleic acid extraction of microorganisms or tissues in the presence of nucleic acid extraction media generally does not require the above temperature control.
