Liquid Nitrogen N2 Freezer

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.

Liquid nitrogen n2 freezer.

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. 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. Space optimization is the goal with every ultra low freezer. 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.

The mean time between failures are another reason to use liquid nitrogen cooled vessels rather than freezers to store biological samples. In applications where storage temperatures above 150 c are acceptable laboratory personnel have had to accept these tradeoffs between usability and reliability in selecting among conventional mechanical and cryogenic refrigeration. Rely on liquid nitrogen to freeze your samples with a wide lab freezer from custom biogenic systems. Liquid nitrogen vs cryogenic freezer.

We stock the latest designs in laboratory freezers so that you can get your work done and stored. Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature.
