Liquid Nitrogen Tank Temperature Range

Last month was a wake up call for cryogenic tank failures in fertility clinics in the us.

Liquid nitrogen tank temperature range.

Over this temperature range liquid nitrogen looks much like boiling water. American biotech supply s box rack storage tanks have been specifically engineered to provide cryogenic vapor temperatures throughout the tank well below the critical 135 c range. At normal atmospheric pressure nitrogen is a liquid between 63 k and 77 2 k 346 f and 320 44 f. It is liquefied under high pressure condition and can expand to a very large volume of gas.

Liquid nitrogen is commonly used across monash university for the purposes of snap freezing and long term storage of biological samples and in cold traps on vacuum lines equipment. Liquid nitrogen is very cold. 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. Liquid nitrogen is one of the cryogenic liquids commonly used in research labs.

As cryogenic means related to very low temperature it is an extremely cold material. Two separate medical centers storing reproductive tissues had failures in their liquid nitrogen tank monitoring. Because liquid nitrogen in a usual setting is boiling its usual temperature is 77 k. Ln 2 liquid nitrogen is a cryogenic liquid and is the liquefied form of nitrogen gas at atmospheric pressure and subzero temperature.

Below 63 k it freezes into solid nitrogen. In fact with as little as 2 inches of liquid vapor temperatures of 185 c or lower can be maintained on. Not only is this a devastating loss for clients but the facilities must endure a.
