Sephadex(R) G-25 is well established gel filtration medium for desalting and buffer exchange in industrial applications.Sephadex(R) is a gel filtration medium prepared by crosslinking dextran with epichlorohydrin. Different types of Sephadex(R) differ in their degree of cross-linking and hence in their degree of swelling and their molecular fractionation range. Sephadex(R) G-25 is one of five different G-types ranging from G-10 for small molecules to G-75 for larger molecules. Sephadex(R) G-25 is available in 4 different particle sizes (Course Medium fine Superfine).Sephadex(R) G-25 is available in different bulk pack sizes and convenient pre-packed formats.As a BioProcess medium Sephadex(R) G-25 meets industrial demands with security of supply and comprehensive technical and regulatory support.
