Chromatography Silica Gel
General Chromatography Silica Gel is a versatile adsorbent composed primarily of silicon dioxide (SiO2) in the form of white beads or irregular particles. Its porous structure and unique adsorption properties make it ideal for various separation and purification tasks. It is mainly used for the refining of petroleum products, to remove aromatic compounds as well as for the preparation of high-purity substances. We have 3 types, Type A, Type B and Type C silica gel powder for chromatography.
