Cole-Parmer Essentials RR-1400 Monobed Deionizer Mixed-Bed Resin; Bulk

Choose from resins and an ultrapure cartidge to provide high purity water from your monobed deionizer water systems.

The mixed-bed resin is made up of a cation and anion bead allowing water to flow through the deionizer tanks and come out near zero totatl dissolved solids, creating deionized water.

The resin is exhausted when chlorine/chlorides leach out. To test, take a beaker of water from the demineralizer and add a drop of silver chloride. If the water is cloudy then the resin should be changed.
