Description
The Thermo Dowex 50WX8 (H), Cat. No: 335350025, is a strongly acidic cation exchange resin in the hydrogen form, encapsulated in a 2.5 KG bottle with Lot: A0438364 and CAS: 11119-67-8. Designed for precision in ion exchange chromatography, low-pressure liquid chromatography, and other cation exchange separation techniques, this resin is composed of a crosslinked styrene-divinylbenzene gel matrix with 8% cross-linkage. Offered in a fine 200-400 mesh bead form, it is particularly effective in applications requiring high resolution and fine particle size, such as water deionization, biochemical separations, and sample purification. Notable for its high exchange capacity of ~1.1 meq/mL, this resin ensures stable and reproducible operation with a moisture content of 50–58%. Ideal for laboratory settings focused on the separation of cationic species including alkali/alkaline earth metals and transition metals.
