Sigma-Aldrich AmberLite™ MB20 Mixed Ion Exchange Resin, H/OH, mixed bed, >50 mesh

Sigma-Aldrich AmberLite™ MB20 is a premium mixed bed ion exchange resin in hydrogen (H⁺) and hydroxide (OH⁻) form, designed for polishing demineralized water to ultra-low conductivity levels (<0.1 µS/cm). This high-quality, nuclear-grade, styrene-divinylbenzene copolymer gel resin consists of a balanced mixture of a strong acid cation (HCR-S [H⁺]) and a strong base anion (SBR [OH⁻]) resin, making it ideal for high-purity water applications, condensate polishing, and in-process deionization.

AmberLite™ MB20 is specially processed to ensure high exchange capacity, rapid kinetics, and consistent bead size, making it suitable for low-pressure liquid chromatography (LPLC), laboratory water purification, and industrial mixed-bed deionization systems.
