Ethanol, an efficient coolant for rapid freezing of biological material.
Supercooled ethanol was used for freeze-quenching protozoan samples and gave reasonable ultrastructural preservation. The use of ethanol as a coolant has considerable advantages in terms of its relative safety, high cooling efficiency and low cost when compared with other coolants currently used for freeze-quenching.
