Description
The Thermo Scientific Dowex 50WX8, new and unused, is a high-quality ion-exchange resin ideal for applications such as ion exchange chromatography, LPLC, and cation exchange separation. Made in the USA, this 2.5 KG bottle features a strongly acidic cation exchange resin in hydrogen form composed of a crosslinked styrene-divinylbenzene gel matrix with 8% cross-linkage. Its 200-400 mesh size provides fine particle size for high-resolution separations, making it effective for water deionization, biochemical separations, and sample purification. Sulfonic acid groups ensure efficient proton exchange, and its high exchange capacity (1.1 meq/mL) guarantees robust performance. With 50-58% moisture content, the resin remains uniformly free-flowing for reproducible column packing at ambient storage conditions. Applications include separation of alkali/alkaline earth metals and transition metals, as well as analytical chemistry and catalysis support.
