Cole Parmer Monobed Deionizer

This deionizer incorporates an ultrapure mixed bed ion exchange resin which contains a 1:1 chemical equivalent of cation and anion resins with a maximum capacity of 1400 grains as CaCO3. Yields water with a resistivity as high as 15 to 18 MΩ-cm.
A built-in monitor ensures water quality. If the resistivity falls below 5 MΩ-cm, the monitor light turns from green to red. To replace the exhausted resin quickly during a momentary shutdown of the system, order the resin refill (order separately). For a faster, more convenient resin replacement, use the ultrapure resin cartridge (order separately), capacity when used with cartridge is 1050 grains as CaCO3. The resin for both the refill and cartridge is an FDA-grade ultraclean resin designed for ultrapure water systems.
