Liquid nitrogen storage: solutions and equipment

Liquid nitrogen storage comes with several safety risks:. A first risk is pressure build-up in the tank or container and the subsequent danger of explosion. If the cryogenic liquid heats up due to poor insulation, it becomes gaseous. One liter of liquid nitrogen increases about 694 times in volume when it becomes gaseous at room temperature and atmospheric pressure.

Liquid nitrogen

The diatomic character of the N 2 molecule is retained after liquefaction.The weak van der Waals interaction between the N 2 molecules results in little interatomic attraction. This is the cause of nitrogen''s unusually low boiling point. [1]The temperature of liquid nitrogen can readily be reduced to its freezing point −210 °C (−346 °F; 63 K) by placing it in a vacuum chamber pumped by a
