Wholesale DL-A23 Strong-Base Type I (Gel) Anion Exchange Resin (UPS) Manufacturer and Supplier

DL-A23 Strong-Base Type I (Gel) Anion Exchange Resin (UPS)

Product Data Sheet

DL-A23 is a uniform particle size high exchange capacity, shock resistant, gel, type I , strongly basic anion exchange resin supplied in the chloride or hydroxide form as moist, tough, uniform, spherical beads.

DL-A23 is intended for use in all type of deionization systems and chemical processing applications and is especially suited for use in regenerable mixed beds. it also shows good kinetics of exchange, enabling very low concentration levels of both strong and weak acid anions to be achieved at practical flowrates.
