Silica gel for column chromatography (silica gel,column chromatography silica gel,silica gel for column chromatography)
Please try SANPONT Silica Gel for column chromatography. We guarantee that our Silica Gel will provide you the excellent results like other higher priced Silica Gel since our Silica Gel is also used by our own laboratory everyday. SANPONT has developed its Silica Gel products to achieve high performance To offer you the best price, we product and sell several mesh sizes and keep simple packaging, and buy directly from our own factory
We carry many grades, 230 - 400 mesh, 100 - 230 mesh, 200 - 300 mesh ,300-400mesh, 60-120mesh and 50 - 80 mesh, etc
Characteristies:
The gel performed as white grains of homogeneous size. Chief ingredient is silicon dioxide. Of high purity. Secure and sanitary
Column chromatography silica gel belongs to colloidal-state system with solid characteristics, which is composed of colloidal particles with condensate structure. The colloidal particle is the polycondensate of hydrated silica gel (multi-silica acid), belongs to a non-crystalline-state substance
The interspace of aggregation of colloidal particle forms the inner micro interspace structure of reagent column chromatography silica gel particle. Therefore, it is a kind of premium quality adsorption material with rich fine porous structure, high specific surface area, high purity and high activity
The performance of column chromatography silica geladsorption, which depends on the fine porous structure and the surface of inner pore formed in process of the raw material silica gel production.
Use:
Separation and refinement of traditional Chinese herbal medicine componentsPreparation of high purity substanceRefinement of petrol productsRemoval of aromatic hydrocarbon material, etcThe prominent advantages of column chromatography silica gel in its application in biology engineering technology
Sanpont products are made from premium quality silica gel with transparency, The silica gel have excellent adsorption performance; It has ideal separation function to similar character and structure, even to isomerIn the production, the time of acid treatment and aging are strictly controlled, also we adopt high-fired technique, so our silica gel have rigid skeleton structure, high mechanical strength,can stand the pressure within 30MPait has good thermal stability and chemical stability, can have selective adsorption and purification of the components of isomer from multi-component solution.in preparation of column chromatography silica gel, a series of products with average pore diameter 20A-20000A can be produced through the control of different process conditions in order to adapt to the separation and purification of the substances with different character, molecular weight and molecular structureSanpont silica gel purity is above 99 ,compared with organic column padding, silica gel is a solid, colloidal gel based on SiO2 matrix,its structure is compact, so even be directly thrown away, the silica gel will not pollute environmentTechnical Data:
