Ethane can be used as a refrigerant in freezing facilities. In scientific research, liquid ethane is used in electron microscopy to make samples with high water content transparent. The thin water layer freezes rapidly upon rapid immersion into the facility's liquid ethane at -150 degrees or less and does not form crystals. Such rapid freezing does not destroy the structure of soft matter in liquid water, as ice does when it crystallizes.
