Acros Organics Dowex 1X8 100-200 Mesh Strongly Basic Anion Exchange Resin 2.5Kg Bottle

The Acros Organics Dowex 1X8 100-200 Mesh is a strongly basic anion exchange resin composed of a polystyrene-divinylbenzene matrix functionalized with quaternary ammonium groups. Designed specifically for laboratory separations, this resin features finely graded bead sizes (100-200 mesh) that provide a high surface area and facilitate rapid ion exchange kinetics essential in analytical chemistry and bioprocessing. Supplied typically in its Chloride (Cl⁻) form, it is optimized for effective separation and purification of anions in various research fields including molecular diagnostics and synthetic biology workflows.

Key technical specifications include:

• Particle Size Distribution: 15% max on 60 mesh, 15% max through 170 mesh for consistent exchange efficiency
• Wet Volume Capacity (Cl form): > 1.2 meq/mL ensuring high ion exchange capacity critical in chromatography and biomanufacturing applications
• Water Retention Capacity: 39-45% (Cl form) aiding in maintaining resin activity under aqueous conditions
• Physical Appearance: Tan to white spherical beads facilitating uniform flow in column applications
• Molecular formula: C29H34ClN with a molecular weight of 432.05 g/mol
• Identification: CAS 12627-85-9, PubChem CID 16212807

This resin is widely adopted in biotechnology laboratories for essential molecular cloning workflows, bioprocess purification steps, and analytical ion-exchange chromatography. The Dowex 1X8 resin supports high-throughput and reproducible results in research and quality control environments requiring precise anion exchange performance. Its robust physical and chemical properties suit it well for integration in biopharmaceutical production pipelines and clinical diagnostics applications.

Packaged in a 2.5 kg bottle, this product originates from the USA and meets stringent specifications for professional laboratory use.
