Acros Organics Dowex 1X8 Strongly Basic Anion-Exchange Resin 100-200 Mesh Beads

The Acros Organics Dowex 1X8 ion-exchange resin (model 203000025) is a strongly basic anion exchanger designed for precise laboratory separations and purification processes. Manufactured in the US, this resin features:

• A polystyrene-divinylbenzene polymer matrix providing chemical stability and robustness
• Quaternary ammonium functional groups facilitating rapid and selective anion exchange
• Particle size of 100-200 mesh ensuring high surface area and fast exchange kinetics critical for analytical ion-exchange applications
• Typical chloride (Cl⁻) form with a wet volume capacity > 1.2 meq/mL and water retention capacity of 39–45%, supporting efficient ion exchange under aqueous conditions
• Physical form as tan to white beads with particle size specifications: max 15% on 60 mesh and max 15% through 170 mesh
• Package weight: 2.5 kg (approx. 3.81 kg metric), supplied ready for laboratory use

This resin is widely used in chromatography, molecular diagnostics, and bioprocessing workflows requiring selective anion removal, purification of biological samples, and water treatment. It is essential for researchers focused on synthetic biology, biotechnology, and biomanufacturing applications where high-efficiency ion exchange performance is critical. The polymer bead format facilitates ease of use in column-packed separations crucial in gene editing and molecular cloning workflows.

Its compatibility with aqueous ion-exchange methods makes it a reliable choice for biomedical engineering, clinical diagnostics, and cell imaging preparative processes. The Dowex 1X8 resin’s strong base character and controlled mesh size distribution ensure reproducible and high-capacity separation essential in advanced laboratory workflows.
