Precise Controlled Atmosphere Glove Boxes provide a leak-tight environment for work with contamination-sensitive materials. Procedures where low levels of oxygen or moisture are important, such as work with organometallics, alternative energy cells or hydrophilic chemicals, are typical applications for these economical glove boxes. Need an ultrapure inert atmosphere? All Precise Controlled Atmosphere Glove Boxes are compatible with the new AtmosPure Re-Gen Gas Purifier accessory, which has the capacity to remove up to five liters of oxygen (13.500 ppm) and 660 grams of moisture (18 million ppm) at standard temperature and pressure (STP).
