Seplife G50 F Dextran Size-Exclusion Medium, 20-80 µm (CAT#: STEM-BC-3185-ZJF)

This dextran chromatography medium is designed for desalting, peptide purification, extract cleanup, and molecular-weight determination. It consists of dextran crosslinked with epichlorohydrin to form controlled pores. Molecules are separated according to their ability to enter the internal gel structure. Excluded large molecules pass through the spaces between particles and elute first. Intermediate molecules enter some pores and move through the column more slowly. Small molecules enter a greater proportion of the pore volume and elute later. The fine particle range supports improved separation efficiency. The stated molecular-weight fractionation range is 1500-30000 Da.
