The scoop on Liquid Nitrogen Dewars

Liquid Nitrogen is a colorless, odorless, noncorrosive and fire-retardant cryogenic liquid that is associated with the specialty gas Nitrogen. Because liquid nitrogen is noncorrosive, special resources for container structure is not necessary. Due to this, liquid nitrogen can be stored in various types of containers. Liquid Nitrogen is shipped in varying forms of containers, [which depends on|depending on|considering]11] the quantity being requested by the customer.

Dewars are one of the various types of containers utilized for liquid nitrogen. They can range in size from 5 to 200 liters. Some of the features of dewars include:


  • A pressure type liquid level gauge
  • Full tricock valve
  • Different relief devices
  • Insulation to for thermal efficiency


These features tend to make the vessels safer and easier to use.

There are a few differences in some dewars, for example portable dewars must have a sturdy construction and casters and are intended for low-pressure transport. Most dewars come with a loose-fitting dust cap over the outlet to stop moisture from the atmosphere from blocking the neck. This also allows the gas formed from the vaporized liquid to escape.
