Our 50 ml conical centrifuge tubes are designed to fit with close tolerance into the 50 ml Solid AluminumTube Holder used in our Mini-Beadbeater-96.  The aluminum holder maintains tube temperature while cells and tissue are being lysed.

Please note:  There are subtle differences in the diameters of other brands of 50 ml screw-cap centrifuge tubes.  That may prevent them from properly fitting into our Aluminum Tube Holder.
