Acros Organics Dowex 1X8 100-200 Mesh Ion-Exchange Resin Beads for Laboratory Separations

The Acros Organics Dowex 1X8 Resin is a high-performance anion exchange resin composed of a polystyrene-divinylbenzene matrix functionalized with quaternary ammonium groups. Featuring a 100-200 mesh particle size, it provides an elevated surface area and rapid ion exchange kinetics, making it essential for laboratory separations and analytical ion-exchange workflows. Supplied in the chloride (Cl⁻) form, the resin exhibits a wet volume capacity exceeding 1.2 meq/mL and a water retention capacity of 39–45%, ensuring reproducible performance in biochemical and molecular diagnostics applications. The physical bead form (tan to white) is well suited for processes such as column chromatography, bioprocessing, and molecular purification steps critical in synthetic biology and biomanufacturing pipelines. This resin supports refined anion removal, purification, and separation tasks widely adopted in biotechnology research and clinical diagnostics. Key technical identifiers include CAS Number 12627-85-9 and molecular weight 432.05 g/mol, underscoring its specific design for precision ion-exchange chromatography. Packaged in a 2.5 kg bottle, this resin is a reliable reagent for researchers focusing on gene editing workflows, bioprocess purification, and fluorescence analysis sample preparation.
