Molecular sieves are used as adsorbent for gases and liquids. Molecules small enough to pass through the pores are adsorbed while larger molecules are not. It is different from a common filter in that it operates on a molecular level and traps the adsorbed substance.
For example, a water molecule may be small enough to pass through the pores while larger molecules are not, so water is forced into the pores which act as a trap for the penetrating water molecules, which are retained within the pores. Because of this, they often function as a desiccant.
We are manufacturing Indicating silica gel & Non-Indicating type of SILICA GEL in all grades such as blue silica gel, orange silica gel and basic silica gel such as type A silica gel , type B silic gel ,type C silica gel and another special silica gel Column chromatography silica gel.
