For more than 30 years, we have used our silica gel technology to provide consistent high-quality media for chromatographic separations. Ashirwad’s Column Chromatography silica gel are available in a wide variety of pore size and particle size distributions with excellent mechanical and structural properties.We offer unmatched capacity for meeting your requirements, from grams to tons. Since we are silica specialists, we also offer an unmatched ability to customize our silica media for your needs. The mixture to be analyzed by column chromatography is applied to the top of the column. The liquid solvent (the eluent) is passed through the column by gravity or by the application of air pressure. An equilibrium is established between the solute adsorbed on the adsorbent and the eluting solvent flowing down through the column. Because the different components in the mixture have different interactions with the stationary and mobile phases, they will be carried along more...

We produce a range of standard size silica gel sachets using non-indicating (white) or self-indicating (orange/green, orange/colorless or blue) silica gels. In the latter case, the colours of the gels are visible through the sachet paper or fabric. Self-indicating silica gel sachets are often useful in test situations, to confirm the suitability of the sachet size chosen, or in cases where an item is frequently inspected and the sachet can be replaced if it has become exhausted. Sachets are manufactured as standard in a heat-sealed non-woven fabric made from 100% viscose fiber with an acrylic binder and polyamide coating. All sachets are printed with Desiccant Silica Gel Do Not Eat We offer various sachet ranges in heat-sealed non-woven fabric and in cloth fabric as below: Grams : 0.5, 1, 2, 3, 5, 10, 15, 20, 25, 40, 50, 100, 250, 500 gram. & 1, 2, 2.5, 4, 5 kg. more...

In our variety of blue silica gel, all the particles of silica gel are impregnated with an indicator. The particles of blue silica gel are blue in colour when it is free from moisture and it is packed at this state in air tight container. As the particles of blue silica gel pick up moisture, it gradually turns pink and gives a ready indication to the user that it has done its work and requires replacement or regeneration. Pink silica gel turns blue when heated to a temperature of 150°C, after drying in sun and can be regenerated indefinite number of times without any loss in absorption efficiency.

Our range of column chromatography has found its place in many laboratories for preparative purposes as well as for reaction control in organic syntheses. It is highly recommended due to following factors:
• Simple packing procedure
• Low operating pressure
• Low expense for instrumentation
Column chromatography is separated into two categories, depending on how the solvent flows down the column.
• If the solvent is allowed to flow down the column by gravity, or percolation, it is called gravity column chromatography.
• If the solvent is forced down the column by positive air pressure, it is called flash chromatography, a "state of the art" method currently used in organic chemistry research laboratories.
Adsorbent particle size affects how the solvent flows through the column. Smaller particles with higher mesh values are used for flash chromatography; larger particles with lower mesh value are used for gravity chromatography. For example, more...- Swambe Chemicals
It is produced by impregnating white Silica Gel with cobalt chloride due to which the colour appearance of Silica Gel is Blue which changes to Pink / White after the moisture is absorbed. It is very easy to ascertain after visualizing whether the moisture absorption capacity is completed or not.Note : It is slightly expensive as compared to non-indicative type. The indicative Silica Gel cannot be used as a moisture detector in the drying of gases containing Ammonia. more...

Our indicating silica gel contains a moisture indicator that is, when silica gel is completely dry, it is deep blue in color and as it picks up moisture from the air, the color indicator changes from blue to pink. This indicating silica gel may be re-dried by heating and it drives off the absorbed moisture, and as it does so, the color changes back to deep blue. Approximately 40g (1.4 oz) of silica gel will absorb the moisture from three cubic feet of air. When drying objects it is important to keep the container size small in relation to the object being dried.
