Competitive Price reagent grade silica gel colomn chromatography powder
Silica Gel Column Chromatography is the most important and widely used techniques for the separation and analysis of complex organic mixtures.
Silica gel for the column purification of organic compounds after the synthesis is done. Used in separation and purification of organic compounds, steroids, amino acids, dyes, alkaloids, phenolic compounds and pharmaceutical intermediates.
Silica gels for column chromatography are available in any desired particle size for pilot plant or plant applications.
Performance: The product is white powder-like particle, which is get through air smashing, extension, filtering and other processing. We add air mixing process into production, which significantly change the shape of particles, the particles are almost circular or elliptical, increase the specific surface area, and improve the separating effect.
Mesh size: 30- 60, 60-120,120-200, 200-400, 60-130, 130-200, 130-230, 130-400 & 230-400.
Usages: Pharmaceuticals Labs, universities, institutes and researching organizations
