Liquid Nitrogen N2 Freezer

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.

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. Lift open the wide lid to access the perfectly arranged racks. 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.

Liquid nitrogen is nitrogen in a liquid state at an extremely low temperature. Space optimization is the goal with every ultra low freezer. The mean time between failures are another reason to use liquid nitrogen cooled vessels rather than freezers to store biological samples. Liquid nitrogen ln 2 is nitrogen in a liquid state at low temperature 195 79 c 77 k.

Liquid nitrogen vs cryogenic freezer. Rely on liquid nitrogen to freeze your samples with a wide lab freezer from custom biogenic systems.
