The column chromatography silica gel 30 A° is made of high quality
silica gel with excellent adsorption properties, which have ideal
separation function for properties, structures and isomers.
The column chromatography silica gelhas good thermal stability and
chemical stability, and is selectively adsorbed and purified
isomers from multicomponent solutions.
In the process of preparation of column chromatography silica gel,
can by controlling the different technological conditions to
produce the average pore diameter of 20 A° to 20000 A° with a range
of products to adapt toisolate pure the different properties,
molecular weight and molecular structure.
Properties:The product is a white odorless powder insoluble in water, acids
and organic solvents. It features uniform pore distribution and
high compressive strength. Because of the high surface hydroxyl
group activity, it can achieve rapid separation and purification
under high and medium pressures.
Application: 1. SPE and FLASH fillers.
2. Used in biochemical research and the production of thin-layer
chromatography analysis plates.
3. Used for the preparation of chromatographic column filler
material, suitable for rapid separation.
Specifications:Include the reagent-grade and the industrial-grade.
500g/bottle (10kg/carton, 20 bottles/carton) 1kg/bag (10kg/carton,
5kg/bag (20kg/carton, 4bags/carton) 25kg/bag (imported kraft coated
25kg/barrel (cardboard or polyethylene or aluminum barrels)
1. The product’s technical indicators and packing forms can be
customized according to customer requirements.
2. The product has a very strong moisture absorption capacity;
therefore, it should be stored in a dry place and pay attention to
ventilation. There should be shelves between the packaging and the
ground. Attention should be paid to protecting the product from
rain, damp and blazing sun.
