Nuclear Grade Strongly Basic Anion Exchange Resin


7170-OH is a premium nuclear-grade strongly basic anion exchange resin of extra high homogeneity, containing typeⅠ trimethylamine functional groups, which is most applicable in the complex-bed or mixed-bed systems of ultrapure water preparations, within a wide range of industries that cover metallurgy, chemical-engineering, nuclear &electric power, electronics, semiconductors, F&B, cosmetics, biopharmaceuticals, etc. Moreover, 7170-OH is often combined with 7320H to be used in single-bed and mixed-bed condensed water processing and electrophoresis refining in various industries.
