For the production of high-purity water as non-regenerable mixed bed
MR-11 is a ready-to-use mixed bed comprsing strongly acidic and strongly basic(type I)gelular cation and anion exchanger. Both components are highly regenerated and specially cleaned. So high purity water can be easily obtained.

MR11 is especially applicable to mixed bed systems for the wire-cutting and as polishing step after DI systems in the production of pure water.
