LabStrong Replacement for Barnstead D3804


The LabStrong D3804LS cartridge kit is comparable to the Thermo Scientific™ Barnstead™ D3804 cartridge kit. Side-by-side testing shows fantastic results for purity and longevity. The D3804LS cartridge kit is used with the Thermo Scientific Barnstead NANOpure™ II and older NANOpure water purification systems. The cartridge kit is an economical alternative for all laboratories.

The NANOpure II Cartridge Kit (4 Module Standard) consists of one D0835LS (Combination Cartridge Colloid/Organic), one D0803LS (High Capacity Two-Bed) and two D0809LS (Ultrapure Mixed-Bed). The LabStrong FL0016-1 Sterile 0.2 Micron Final Filter with Endbell, which is comparable to the Thermo Scientific Barnstead D3750 Final Filter, is included with the kit. The LabStrong 06808LS Quad Style Canister O-Rings, which are comparable to the Thermo Scientific Barnstead 06808 and 06808-DB Quad Style Canister O-Rings, are included with the kit. LabStrong takes extra care in sealing our water purification cartridges to ensure exceptional quality is maintained throughout the two year shelf life. Each cartridge is sealed in a military specification vapor barrier foil Mylar bag, which dramatically inhibits drying out of the resin.
