The D3807LS cartridge kit is comparable to the Barnstead* D3807 cartridge kit. The NANOpure II Cartridge Kit (4 Mod Organic Free) consists of one D0836LS (PreTreat: Colloids, Organic, Carbon), one D0803LS (High Capacity Two-Bed), one D0809LS (Ultrapure Cartridge, Mixed Bed) and one D0820LS (Organic Free). We take extra care in sealing our cartridges multiple ways, ensuring exceptional quality is maintained throughout the two year shelf life. Each cartridge has fitted sealing plugs/caps placed on both ends, and then it is further sealed in a military specification vapor barrier foil bag – the combination of which dramatically inhibits drying out of the resin beads.
