Thermally conductive glass beads eliminate the water bath worries of evaporation and contamination, dripping vessels, and constant cleaning. Tubes and flasks are supported without the need for racks or weights. Glass beads may also be used with cooling blocks or dry ice in ice buckets. For added convenience, freeze the beads in a MicroBead nylon drawstring bag.

Thermal MicroBeads measure 2.5-3 mm in diameter and are autoclavable and solvent resistant.
