Hydroxypropylated Dextran Gel Filtration Resin

• Product Overview: Hydroxypropylated Dextran Gel Filtration Resin is a size-exclusion chromatography resin prepared by hydroxypropylation of cross-linked dextran microspheres (the gel filtration resin Gel Filtration Resin). After hydroxypropyl modification, the highly hydrophilic dextran becomes moderately lipophilic and is compatible with both aqueous and organic solvent systems.
  This product is widely used for the separation and purification of steroids, terpenes, lipids, and low-molecular-weight peptides in organic solvents. It is also suitable for extracting active ingredients from herbal medicines and for fine purification of antibiotics and chemical drugs.
