Super wide pore silica gel is milky particle, its main ingredient is SiO2·nH2O,indissolvable in water and inorganic acid,dissolvable in hydrofluoric acid and thick caustic alkali solution.

This product is mainly used as catalyst and catalyst carrier;used for determination of the molecular weight of high polymer in gel chromatography;used for separation of such macromolecule as protein and nucleic acid;Used for refining and purifying biological active substance as well as chemical synthesis substance, used for separation of high polymer and as the carrier of gel chromatography, meanwhile, it is also the basic raw material for preparation of other fine silica gel products. This product is milky granular or spherical silica gel or can be processed into powder at the request.
