Liquid Nitrogen Storage Freezer

Liquid nitrogen box quick freezing machine is consisted of insulation layer fans controller solenoid valve ln2 injectors and pipelines.

Liquid nitrogen storage freezer.

Round space saving design. Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. Modern vapor phase liquid nitrogen freezers are so well insulated that the sample space temperature is maintained at or below 190 c even if the lid is kept off. Stainless steel vacuum insulated vessel.

A tank of liquid nitrogen used to supply a cryogenic freezer for storing laboratory samples at a temperature of about 150 c controlled rate and slow freezing also known as slow programmable freezing spf 15 is a set of well established techniques developed during the early 1970s which enabled the first human embryo frozen birth zoe leyland during 1984. In an incident on january 12 2006 at texas a m university the pressure relief devices of a tank of liquid nitrogen were malfunctioning and later sealed as a result of the subsequent pressure buildup the tank. It need to be connected to liquid nitrogen storage tank or liquid nitrogen supply pipe through pipeline for using. It is a colourless clear liquid with a density of 0 807 g ml at its boiling point 195 79 c 77 k.

Benefits to the custom biogenic systems standard liquid nitrogen freezer. Ease of operation plus flexibility to operate vapor storage immersion storage or a combination of both to store any type or size of sample. Our range of cryogenic freezers offers something for everyone from traditional liquid nitrogen storage to our mve heco series next generation high efficiency freezer. 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.
