Aluminium has excellent thermal conductivity properties and good corrosion resistance. With these properties, small aluminum beads have become a popular substitute for water in a laboratory bath. There are several advantages: Heated bead baths can be left on so they are always ready to use without monitoring and refilling; cooling buckets can be left in a refrigerator or freezer until needed, vials or tubes inserted into the beads are firmly supported and do not tip over or sink, risk of contamination from the water is eliminated, the beads are easy to decontaminate and sterilize, and the energy efficiency of the baths are improved by a factor of 2 or 3. While spherical-, raisin- or cylindrical-shaped aluminum “beads” available from other suppliers can provide the above improvements, BioSpec’s Tiny Teardrops™ aluminum beads go a step further. Their shape permits higher packing densities and 10X greater surface-to-surface contact for improved heat conduction.
