We offer TLC Grade Silica Gel, which is a Thin Layer Chromatography silica gel. The Silica gel with calcium sulphate (CaSO4 ½ H2O) as binder is extensively used adsorbent in Thin Layer Chromatography because of the excellent separation it affords. When coated on a plate in the form of thin layer, silica serves as a versatile solid stationary phase for adsorption and partition chromatography.

We offer Silica Gel Sachets, which contain silica gel of suitable particle size. They are heat sealed in non woven fabric (Paper) and stitched in perforated cotton cloth. The Silica Gel Sachets can withstand friability test thus the silica gel inside does not disintegrate into fine particles and does not pass through the packing material. The non woven fabric or perforated cloth used as packaging materials in the Silica Gel Sachets is permeable to moisture to facilitate the dehumidifying or drying process. Both types- Indicating (Blue) or non-indicating (White) silica gel are available in the sachet. Sachet using indicating silica gel has blue tinge in activated state. In case non-indicating it does not give such indication. The active self-indicating (Blue) silica gel sachet gives a clear sign that an item is safe from further detoration from moisture.
All the sachets are printed with "DESICCANT SILICA GEL – DO NOT EAT". The packs can also be printed with customized texts.
Perporated cotton sachets are available in the range from 25gm to 1kg, to withstand the weight of Silica gel. Non woven Fabric (paper) sachets are available from 0.5gm to 100gms.

We offer Granular Silica Gel which the grainy porous transparent substance with a good surface area for adsorption of water and organic/gaseous molecules. Silica gel can adsorb 2540% moisture by weight. Our Granular Silica Gel are available in different mesh sizes. They are blue in colour and turn pink as it starts absorbing moisture in the activated state. The blue color is an indicator of complete activation while non-indicating is white in color. This is why Granular Silica Gel are the preferred desiccant or adsorbent.
