Krypton, Kr Specialty Gas

Krypton is a rare atmospheric gas which is colorless, tasteless, odorless, nontoxic, and chemically inert. The concentration of Krypton in the atmosphere by volume percent is 1.1 x 10-4. Krypton is principally shipped and used in gaseous form for excimer lasers, light bulbs, window insulation and R&D laboratory research.

Safety Requirements: The cryogenic liquid will rapidly boil into a gas at standard temperatures and pressures. The liquefied gas can cause frostbite and contaminate any tissue in proximity. The main health hazard associated with release of this gas is asphyxiation by displacement of oxygen (see MSDS for further information).
