The scoop on Liquid Nitrogen Dewars in Portland

Liquid Nitrogen is a colorless, unscented, noncorrosive and fire-retardant cryogenic liquid that has the same properties as 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 many different types of containers. Liquid Nitrogen is distributed in varying forms of containers, [which depends on|depending on|considering]11] the amount the buyer would like to receive.

Dewars are one of the many different types of vessels utilized for liquid nitrogen. They can range in volume 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 strong construction and casters and are meant for low-pressure transport. Most dewars come with a loose-fitting dust cap over the outlet to stop moisture from the air from blocking the neck. This also allows the gas produced from the liquid that becomes a vapor.
