Liquid nitrogen storage freezer.

Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. Modern vapor phase liquid nitrogen freezers are so well insulated that the sample space temperature is maintained at or below 190 c even if the lid is kept off. Because the liquid to gas expansion ratio of nitrogen is 1 694 at 20 c 68 f a tremendous amount of force can be generated if liquid nitrogen is vaporized in an enclosed space.
