More Information Cryobiologists can now design their own cryosubstitution procedure at various temperatures, using most any laboratory freezer, with our uniquely designed heat sinks. The standard heat sink is made of aluminum and measures 6 x 9 x 2 and has space for eighteen standard scintillation vials.
All heat sinks come with a standard protocol for freeze-substitution.
This product is used in cryobiology laboratories doing ultrarapid freezing, vitrification and controlled-rate freezing.
