What is Liquid Nitrogen?
Liquid Nitrogen is chilled, condensed gaseous nitrogen. It is also colorless, odorless, non-flammable, and non-toxic. It is also extremely cold (LN2 boils at -324 F or -210 C) and because of this intense cold, handling this material requires the use of protective gloves and goggles. Liquid Nitrogen is normally referred to as “LN2”.
