Learn more about the different gases commonly used in biotechnology.
N₂
Liquid nitrogen is essential for cryogenic preservation of cells, tissues, and genetic materials at -196°C. Liquid nitrogen maintains biobanks, enables flash freezing of samples, and provides an inert atmosphere for oxygen-sensitive reactions and storage.
CO₂
Critical for maintaining pH balance in cell culture incubators through bicarbonate buffering systems. CO₂ is also used in supercritical fluid extraction to isolate bioactive compounds and in controlled atmosphere storage.
O₂
Supports aerobic cell cultures and fermentation processes in bioreactors. Oxygen enables cellular respiration for mammalian cell lines and aerobic microorganisms used in protein production and biotechnology research.
Ar
Provides ultra-pure inert atmosphere for sensitive biochemical reactions and prevents oxidation of reactive compounds. Argon also serves as a plasma gas in ICP-MS for trace element analysis of biological samples.
He
Used as a cryogenic coolant for NMR spectroscopy and MRI systems. Helium serves as an inert carrier gas in gas chromatography for analyzing biological compounds and provides leak detection for vacuum systems.
