Silica gel was patented by chemistry professor Walter A. Patrick at Johns Hopkins University, Baltimore, Maryland in 1919. Prior to that, it was used in World War I for the absorption of vapors and gases in gas mask canisters. The substance was in existence as early as the 1640s as a scientific curiosity.[1]
In World War II, silica gel was indispensable in the war effort for keeping penicillin dry, protecting military equipment from moisture damage, as a fluid cracking catalyst for the production of high octane gasoline, and as a catalyst support for the manufacture of butadiene from ethanol, feedstock for the synthetic rubber program. more...

However, some packaged desiccants may include fungicide and/or pesticide poisons. It is not known whether these would be labelled specifically. Food-grade desiccant should not include any poisons which would cause long-term harm to humans if consumed in the quantities normally included with the items of food. more...

Silica gel's high surface area (around 800 m²/g) allows it to adsorb water readily, making it useful as a desiccant (drying agent). Once saturated with water, the gel can be regenerated by heating to 150 °C (300 °F) for 1.5 hours per litre of gel. Some types of silica gel will "pop" when exposed to enough water. more...

In chemistry, silica gel is used in chromatography as a stationary phase. In column chromatography the stationary phase is most often composed of silica gel particles of 40-63 µm. In this application, due to silica gel's polarity, non-polar components tend to elute before more polar ones, hence the name normal phase chromatography. However, when hydrophobic groups (such as C18 groups) are attached to the silica gel then polar components elute first and the method is referred to as reverse phase chromatography. Silica gel is also applied to aluminum or plastic sheets for thin layer chromatography. 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:

We are one of the renowned manufacturers of white silica gel, an amorphous form of silicon dioxide. It is synthetically produced in the form of hard irregular granules (having the appearance of crystals) or hard regular beads as per requirement. The micro porous structure of interlocking cavities gives a very high surface area (800 square meters per gram) making silica gel a high capacity desiccant. Water molecules adhere to the gels surface and exhibit a lower vapor pressure than the surrounding air. When equilibrium of equal pressure is reached, no adsorption takes place. Higher the humidity of the surrounding air, the greater will be amount of water that is adsorbed before reaching equilibrium. In higher humidity conditions (above 50% Relative Humidity), stored or in-transit items are susceptible to damage. The unique quality of silica gel is the physical adsorption of water vapor into its internal pores with no by products or side effects or chemical reaction. When it gets more...

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 with more...

We are also the leading exporter of impeccable quality Silica Gel Sachets. Available at most competitive rates, it can prevent moisture damage to electrical goods and electronic components (internally and externally), communication equipment, metallic parts, leather goods, tools and many other small to medium sized items in use, store or transit. Ranging from 0.5gm to 1Kg storage capacity, theses sachets adsorb water vapour whilst remaining dry to touch, providing superb moisture protection. This product is 99% silicon dioxide (SiO2) and has the characteristic of absorbing water from the atmosphere even under low relative humidity conditions.
Silica gel sachets or bags, are simply flexible 'containers ' of silica gel. The sachet material has to be robust and capable of withstanding normal handling whilst importantly being able to breathe. This means that water molecules can pass through the material and be adsorbed by the silica gel. Standard sachet materials are tea-bag paper, fabric, cotton or Tyvek?. Some sachets have heat-sealed seams, others are sewn.
In this type all the gel particles are impregnated with an indicator. When free from moisture the crystals of silica gel are blue. As they are put to use, the crystals can take up moisture, it gradually turns pink and gives a ready indication that done its work and need replacement or regeneration.
Engaged in offering blue silica gel with following features: Blue Silica gel is also known as Self Indicating Silica Gel as it is prepared by impregnating White Silica gel with Cobalt Chloride present in a concentration of 0. 5 to 1% weight for weight, an indicator, which provides the Blue color appearance. Self-indicating Silica Gel will adsorb moisture in exactly the same way as standard non-indicating (white) silica gel but will actually indicate when they are becoming saturated by changing their colour from blue to pink thus indicating that it has adsorbed moisture and needs to be replaced.
