Bulk silica gel
Characteristics of bulk silica gel
Bulk silica gel is a versatile method of protecting your products against damage from moisture and damp during transport and storage. It is used above all in industrial drying plants, in laboratories, in compressed air drying and in pressure compensation containers. It is an outstanding substance for the drying of air and gases.
Mode of action of bulk silica gel
Bulk silica gel consists of hard, vitreous pearls made of silicon dioxide. Its large inner surface has an extremely high water adsorption capacity. The silica gel adsorbs water molecules. The structure of the water does not change; it retains its form and can be emitted during regeneration.
Application of bulk silica gel
The handling is extremely easy and flexible. The required quantity of silica gel is simply distributed in the closed area that requires drying. It can be spread loosely or placed in additional containers.
Bulk silica gel white is filled into air-proof packaging as pouches or sacks. Silica gel white has the capacity to regenerate, which makes it very environmentally compatible. It is regenerated by heating in an oven at 100-150 °C.
The special feature of silica gel 60
Silica Gel 60 is used very frequently in analytical chemistry. The chemical properties of Silica Gel 60 make it particularly suitable for column chromatography. The fine white powder made of silicon dioxide has the perfect structure to filter and separate substances, as it is highly hygroscopic.
Silica Gel 60 is available in two granule sizes, namely fine and extra fine. The following applies: The finer the Silica Gel 60, the greater its water adsorption capacity, even at low relative humidities.
