Liquid nitrogen is a compact and readily transported source of dry nitrogen gas, as it does not require pressurization. Further, its ability to maintain temperatures far below the freezing point of water makes it extremely useful in a wide range of applications, primarily as an open-cycle refrigerant, including: In cryotherapy for removing unsightly or potentially malignant skin lesions such as warts and actinic keratosis. To store cells at low temperature for laboratory work. In cryogenics. As a source of very dry nitrogen gas. For the immersion, freezing, and transportation of food products. For the cryopreservation of blood, reproductive cells (sperm and egg), and other biological samples and materials. To preserve tissue samples from surgical excisions for future studies.
