At CRS, we manufacture gas purifiers and traps to meet your laboratory needs. Individual cartridge systems are designed for specific contaminant removal, such as our oxygen traps, moisture traps and hydrocarbon traps. We have an All-In-One Gas Purification System, a one cartridge design to remove oxygen, water, and non-methane hydrocarbons. Our Advanced Filter System has a high capacity and efficiency in a single cartridge, with two visible indicators for oxygen and water. We also carry a line of ZPure™ Purifiers that are compact in design to fit many existing installations that use small aluminum filters. We offer a regeneration service for our filters, please contact us for more information.
