Seplife G25 M Dextran Size-Exclusion Medium, 50-150 µm (CAT#: STEM-BC-3183-ZJF)

This dextran size-exclusion medium is designed for preparative desalting and purification of peptides and small molecules. It is formed by crosslinking dextran with epichlorohydrin through ether bonds. The resulting three-dimensional gel network separates molecules according to size. Large molecules cannot enter the pores and therefore move through the bed rapidly. Intermediate molecules enter part of the internal pore volume. Small molecules penetrate more of the matrix and elute later. The medium particle size supports preparative column operation. Its stated molecular-weight separation range is 1000-5000 Da.
