The D4801LS cartridge kit is comparable to the Barnstead* D4801 cartridge kit. The NANOpure Quad Style Cartridge Kit (Tap Feed / Standard) consists of one D0835LS (Combination Colloid, Organic, Carbon), one D0803LS (High Capacity Two-Bed) and two D5027LS (Ultrapure Mixed Bed). 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. The O-Ring Canister Seals are included with the kit.
