Acros Organics Dowex 50WX8 Strong Acid Cation Exchange Resin 100-200 Mesh

The Acros Organics Dowex 50WX8 is a *high-efficiency strong acid cation exchange resin* widely used in analytical separations, deionization, and sample preparation workflows essential for molecular diagnostics and bioprocessing. This resin features:

• Mesh size: 100-200 mesh with particle distribution limits (max 15% on 60 mesh cumulative, max 15% through 170 mesh), optimizing flow and exchange kinetics.
• Chemical structure: Sulfonic acid functional groups enabling high cation exchange capacity, with a minimum wet volume capacity of 1.7 meq/mL in hydrogen form.
• Form: Supplied as moist beads or spheres, insoluble in water to maintain resin stability during biopharmaceutical production pipelines.
• Water retention: 50-58% in H form, ensuring reproducible ion-exchange performance in aqueous systems.
• Color and packaging: Beige to brown resin supplied in plastic bottles, chemically identified as AmberChrom 50WX8 (CAS 11119-67-8, MDL MFCD00132726).

This resin is critical in biotechnology applications, including molecular cloning workflows and synthetic biology research, where precise ion exchange plays a vital role in buffer preparation, desalting, and purification. Its robust polymer backbone and strong acid cation exchange groups allow consistent performance in biomedical engineering, cell imaging assays, and clinical diagnostics.

The Dowex 50WX8 resin is a polymer-based ion exchanger falling under harmonized code 39140000, making it compliant with regulatory classifications for laboratory reagents. Its high capacity, well-defined particle size distribution, and water retention support biomanufacturing processes requiring reliable and reproducible ion exchange resins widely adopted in cutting-edge biotechnology research.
