The AtmosPure™ Re-Gen Gas Purifier reduces the levels of oxygen and
moisture inside the controlled atmosphere glove box. The Gas Purifier
enables the user to work in an inert gas environment with materials that are
sensitive to oxygen and moisture. The Gas Purifier comes fully regenerated
and ready to use after the main chamber oxygen and moisture levels are
reduced to 3000-5000ppm using evacuation and re-fills of an inert gas. The
Gas Purifier has been tested with all three controlled atmosphere glove box
liner materials manufactured by Labconco (stainless steel, fiberglass (FRP),
and polyethylene). All three Labconco controlled atmosphere glove boxes
meet or exceed ISO 10648-2 standards when used with the Gas Purifier. The
test results are as follows:
