SM15 Mixed bed Resin for Wire-cutting
Product InformationFor the production of high-purity water as non-regenerable mixed bed SM15 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. SM15 is especially applicable to mixed bed systems for the wire-cutting and as polishing step after DI systems in the production of ultrapure water.General Description
