SANPONT products and sells high quality Silica Gel for column chromatography with the lowest everyday price to many research institutions and labs

SANPONT has developed high quality Silica Gel to achieve excellent column chromatography results

SANPONT Silica Gel Advantages:
High quality fresh Silica Gel used by SANPONT own factory lab
Free Sample : you can test the performance before buying

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

Silica Gel 230 -400 mesh
This mesh size is suited for flash (low pressure) chromatography. Its much smaller particle size gives excellent separation result with pressurized column. This is the most commonly used mesh size in organic synthesis labs

Use
Separation and refinement of traditional Chinese herbal medicine components
Preparation of high purity substance
Refinement of petrol products
Removal of aromatic hydrocarbon material, etc

The 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 isomer
In 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 30MPa
it 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 structure
Sanpont 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 environment
