Macroporous Strongly Basic
Styrene-based Mixed-bed Anion Exchange Resin


D201MB is a premium grade macroporous strongly basic anion exchange resin of type I. With its highly uniform and solid structure, it performs with good anti-osmatic efficiency and shock resistance. It is mainly combined with D001MB to be used in processing mix-bed pure and ultrapure water preparations, with equivalent properties as US Model #IRA-900.
