FAQ: Where To Buy Liquid Nitrogen For Science Experiments?

How do you get liquid nitrogen?

Liquid nitrogen is produced commercially from the cryogenic distillation of liquified air or from the liquefication of pure nitrogen derived from air using pressure swing adsorption.

What material can hold liquid nitrogen?

Low carbon, 3.5%-nickel steels are often used in liquid gas storage tanks at temperatures down to -100°C. Many aluminium, nickel, and titanium alloys are also suitable for these temperatures.

What can you freeze with liquid nitrogen?

  • Loss of pigmentation.
  • Loss of hair in treatment area.
  • Bleeding and blisters.
  • Healing problems.

How do you die from a liquid nitrogen leak?

Liquid nitrogen gas released in a confined space can displace sufficient oxygen to make the atmosphere incapable of sustaining life and cause asphyxiation without warning. Degrees of asphyxia will occur when the oxygen content of the working environment is less than 20.9% by volume.
