Acros Organics Dowex 1X8 Ion-Exchange Resin, 100-200 mesh, 2.5 kg Bottle

The Acros Organics Dowex 1X8 is a strongly basic anion-exchange resin supplied in a 2.5 kg bottle, widely used for laboratory separations and analytical ion-exchange applications. Constructed from a polystyrene-divinylbenzene matrix embedded with quaternary ammonium functional groups, this resin features a 100-200 mesh particle size ensuring a high surface area and rapid exchange kinetics essential for effective anion separation and purification.

Key technical specifications include:

• Physical form: Tan to white beads
• Particle size distribution: ≤15% max on 60 mesh, ≤15% max through 170 mesh
• Wet volume capacity: >1.2 meq/mL (chloride form)
• Water retention capacity: 39–45% (chloride form)
• Molecular weight: 432.05 g/mol, molecular formula C29H34ClN
• Supplied in chloride (Cl⁻) form for consistent ion-exchange performance

This resin is critical in biotechnological purification workflows, including molecular diagnostics, bioprocessing, and biopharmaceutical production pipelines, where precise ion separation impacts overall experimental reliability. Its strongly basic nature and rapid kinetics make Dowex 1X8 widely adopted in research domains such as synthetic biology, cell imaging sample preparation, and clinical diagnostics requiring efficient anion removal.

Manufactured in the United States, this resin ensures reliable performance in both laboratory-scale and scale-up biomanufacturing applications. It is broadly compatible with various chemical separation processes fundamental to biotechnology research and molecular cloning workflows.

Use this high-capacity ion-exchange resin to optimize your analytical methodologies and purification protocols involving anionic species in complex biological and chemical matrices.
