Understanding Liquid Nitrogen: Uses and Safety Measures
网页LN2 is essentially nitrogen in a liquid state, achieved by cooling nitrogen gas to extremely low temperatures. With a boiling point of about −196 °C (−321 °F; 77 K), liquid nitrogen is utilized as a highly efficient coolant in various industries due to its ability to maintain temperatures far below freezing.

Working with Liquid Nitrogen - Lab Manager
网页2019年11月4日 — LN 2 is classed as a cryogenic fluid, being a liquefied gas that must be kept at extremely low temperature. Boiling points for cryogens are defined as below -150°C (-238°F). LN 2 boils at -196°C (-320°F). This fact presents the primary hazard: contact will produce severe burns and more serious injuries due to instant freezing.
