Liquid Nitrogen Introduction And Information About Handling Safely

Edit: Henan Tianchi Instrument Equipment Co., Ltd    Date:2017-08-28
         Here are some Liquid nitrogen simple introduction and information about handling liquid nitrogen safely.
         Liquid nitrogen is the liquefied form of the element nitrogen that is commercially produced by fractional distillation of liquid air. Like nitrogen gas, it consists of two nitrogen atoms sharing covalent bonds (N2).
         Sometimes liquid nitrogen is denoted as LN2, LN, or LIN.
         At normal pressure, liquid nitrogen boils at 77 K (−195.8°C or −320.4°F).
         Liquid nitrogen boils to fill a volume with nitrogen gas very quickly.
         Nitrogen is non-toxic, odorless, and colorless. It is relatively inert. It is not flammable.
         Nitrogen gas is slightly lighter than air once it reaches room temperature. It is slightly soluble in water.
         Liquid nitrogen is stored in special insulated containers that are vented to prevent pressure build-up. Depending on the design of the tank, it can be stored for hours up to a few weeks.
