Krypton, Kr Specialty Gas

Krypton is principally shipped and used in gaseous form for excimer lasers, light bulbs, window insulation, and R&D Labs.Krypton is a rare atmospheric gas that is colorless, tasteless, odorless, non-toxic, 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.

Krypton 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 of releasing this gas is asphyxiation by oxygen displacement (see SDS for further information).
