Oxygen Free/Anoxia for Storage and Display

Anoxic (oxygen-free) conditions are used for the storage of fragile organic artefacts, as well as for pest control. Anoxia is also used to store sensitive metals (such as archeological iron) and minerals (pyrites) to prevent corrosion. Hypoxic (reduced oxygen) conditions are used to provide fire-proof storage of archives.

Anoxic environments can be created by a variety of means. The simplest method is created using only a well-sealed container (usually made of a flexible barrier film, such as Escal), and Ageless oxygen absorber. Anoxic environments can also be created by displacing the air with a purge of nitrogen or argon gas.

Oxygen-free conditions are occasionally used for anoxic museum display, which may be achieved using either active and passive methods. All anoxic display methods require superbly designed and sealed showcases, as well as an investment in monitoring and maintenance.

Keepsafe Microclimate Systems offers expertise in many aspects of low oxygen storage and display, including access to state-of-the-art nitrogen generators, active humidity controllers, passive humidity buffering, Escal barrier films, and Ageless and RP System oxygen absorbers.
