GLOSSARY: Liquid Nitrogen

A material that can be used to passively control temperature in the transit of medicines.

Advantages: Not difficult to procure, long staying power – can last for 8–10 days for a shipment. Can maintain temperatures of sub -80°

Limitations: Hazardous – If shipping by air considerations must be made. Also the careful handling of dewars must be applied as to not displace the nitrogen. Liquid nitrogen solutions tend not to embody larger capacities – no full pallet or larger sizes.
