How can Liquid Nitrogen be Stored?

Liquid nitrogen is stored in special insulated containers that are vented to prevent pressure build-up. Depending on the design of the dewar or flask, it can be stored for hours up to a few weeks.

What is the boiling point of Liquid Nitrogen?

Nitrogen is in a liquid state when at a very low temperature. Liquid nitrogen boils at 77 kelvin (−196 °C, −321 °F). LN2 displays the Leidenfrost effect, which means it boils so rapidly, it surrounds surfaces with an insulating layer of nitrogen gas. This is why spilled nitrogen droplets skitter across a floor.
