Column Chromatography Silica Gel 90A °

 

Properties: The product is a kind of strong polarity solid adsorbent, which is chemically stable, uniformly distributed in pore size, and strong in carrying capacity. Its main component is silicon dioxide. The product is processed and prepared from quality silica gel that has a uniform pore structure. Because the duration of different material components adsorbed on this silica gel is different, it can be used to separate and purify the mixed components.

Application:It is widely used in pharmaceutical science, plant science, bio-engineering, fine chemical engineering, organic synthesis, material science and technology, life science, environmental science, research institutes and other fields.

Specifications: Include the reagent-grade and the industrial-grade.

Package:

500g/bottle (10kg/carton, 20bottles/carton)     1kg/bag (10kg/carton, 10bags/carton)

5kg/bag (20kg/carton, 4bags/carton)     20kg/bag (imported kraft coated woven bags)

20kg/barrel (cardboard, polyethylene or aluminum barrels)

Warm Tips:

1. Both the technical index and packaging of the product can be customized.

2. The product has a very strong moisture absorption capacity; therefore, it should be stored in a dry and ventilated place. Shelf racks should be put between the container and the floor. The product should be kept from rain, moisture and sunshine during transportation.
