LabStrong Replacement for Barnstead D50227


The LabStrong D50227LS cartridge kit is comparable to the Thermo Scientific™ Barnstead™ D50227 cartridge kit. Side-by-side testing shows fantastic results for purity and longevity. The D50227LS cartridge kit is used with the Thermo Scientific Barnstead E-Pure™ ultrapure water purification systems. The water purification cartridge kit provides outstanding quality you expect from your water system at a low cost. The cartridge kit is an economical alternative for all laboratories.

The E-Pure Cartridge Kit (Pretreated Feed/4 Module Standard) consists of one D0835LS (Combination Cartridge Colloid/Organic), one D0809LS (Ultrapure Mixed-Bed) and two D5027LS (Ultrapure Mixed-Bed). The LabStrong GSX28LS O-Ring Canister Gaskets, which are comparable to the Thermo Scientific Barnstead GSX28 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.
