Dessicant Silica Gel
（for MILITARY specification silica gel, please contact us�
The microporous structure of silica gel affords a high surface area (up to 800 m2/g) that is ideal for the scavenging of atmospheric moisture. Since there is no chemical reaction associated with the dehydration process, desiccated compounds are never exposed to harmful by-products or contaminants.
Silica gel is used widely as a laboratory desiccant for the following reasons:
It can adsorb up to one third of its own weight in water vapour (this adsorption efficiency is approximately 36% greater than that of typical desiccant clays)
It has an almost indefinite shelf-life if stored under airtight conditions
Once saturated with water, silica can be regenerated by gentle heating
With the exception of strong alkalis and hydrofluoric acid (HF), it is inert and resistant to attack or corrosion
It is non-toxic, non-flammable and easy to handle
It maintains the appearance of a dry product and its shape remains unchanged even when fully saturated with water
Standard white silica gel is referred to as being non-indicating. Self-indicating silica gels possess a chemical compound or dye that changes colour as moisture is adsorbed.
Our self-indicating desiccants are available in “blue to pink�and “orange to green or white�format. Please note that medium size granules (1 �5 mm) are suitable for laboratory desiccants whilst larger granules (2 �5 mm or 4 �8 mm) are normally employed in dynamic adsorption processes. |
