Cryogenic equipment is used to store biologic, genomic, and diagnostic samples in liquid nitrogen (-196°C to -210°C). Cryogenic freezers are available for controlled freezing of samples requiring slow cooling. Equipment for safely storing and transporting samples in liquid nitrogen is available, including tubes and boxes for storing samples, equipment for grinding frozen samples, and vessels for transporting liquid nitrogen.

Liquid nitrogen storage devices range in capacity from 1 liter to close to 200 liters. They may also be grouped by the number of samples they can accommodate.

Equipment and supplies for safely storing and transporting samples in liquid nitrogen include sample storage tubes and boxes, equipment for grinding frozen samples, liquid nitrogen transfer products, liquid nitrogen storage tanks, and vessels that hold or transport liquid nitrogen.
