Liquid Nitrogen N2 Freezer

Liquid nitrogen ln 2 is nitrogen in a liquid state at low temperature 195 79 c 77 k.

Liquid nitrogen n2 freezer. The mean time between failures are another reason to use liquid nitrogen cooled vessels rather than freezers to store biological samples. It is a colourless clear liquid with a density of 0 807 g ml at its boiling. 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. Rely on liquid nitrogen to freeze your samples with a wide lab freezer from custom biogenic systems.

Following more than 100 years of manufacturing experience the vacuum insulation of a robust stainless steel vessel rarely fails while electrical freezers heat up within hours after an electricity interruption or a compressor failure. We stock the latest designs in laboratory freezers so that you can get your work done and stored. 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. 320 f boiling point at sea level it is produced industrially by fractional distillation of liquid air it is a colorless low viscosity liquid that is widely used as a coolant.
