Seplife G50 SF Dextran Size-Exclusion Medium, 10-40 µm (CAT#: STEM-BC-3187-ZJF)

This superfine dextran chromatography medium is designed for desalting, peptide separation, extract cleanup, and molecular-weight determination. It uses a crosslinked dextran matrix with a controlled porous network. Components are separated according to their molecular size and ability to enter the pores. Large molecules are excluded from the matrix and therefore elute first. Intermediate molecules enter a portion of the pore structure and elute later. Small molecules access more internal volume and experience the greatest delay. The 10-40 µm particles support high chromatographic resolution. The stated fractionation range is 1500-30000 Da.
