Designed to replace the water in standard baths, the thermal metallic beads transfer heat to contained materials without the risk of splashing or evaporating. The dry balls are naturally less susceptible to microbial growth than fluids, and therefore are less likely to contaminate procedures by housing organisms. With a uniform shape, the metallic beads conform to the contained materials and evenly distribute heat to prevent distorted data.
