Description
The Thermo Scientific Dowex 50WX8, a new 200-400 mesh ion-exchange resin, is an essential tool for effective cation exchange chromatography. This ion-exchange resin, in the hydrogen form, is composed of a crosslinked styrene-divinylbenzene gel matrix, providing both mechanical and chemical stability with its high 8% cross-linking. Supplied in bead form, ideal for high-resolution separations and small-volume applications, it has a high exchange capacity of approximately 1.1 meq/mL. The Dowex 50WX8 is widely used in techniques such as ion exchange chromatography and low-pressure liquid chromatography (LPLC), making it perfect for water deionization, biochemical separations, and sample purification. Packaged in 2.5 KG bottles, this resin is ready-to-use for deionization and protonation reactions.
