Glassy, hard, irregular shaped granules with a very high purity of SiO₂ and an internal surface of approx. 800 m²/g. Because of its very large surface area, this silica gel exhibits a high adsorption for water vapour.

Supplier: VWR Chemicals

Our silica gel yellow/blue is used where products need to be protected from humidity during storage and transportation. The colour changes from yellow to light blue when saturated.

Supplier: HICHROM

Prevail™ HPLC columns exhibit long column lifetime in both highly aqueous and highly organic mobile phases. All phases, apart from Prevail™ Carbohydrate ES are silica-based. The stability of these phases is such that a single column can be switched between highly aqueous for analysis of highly polar analytes and highly organic for strong retention of hydrophobic analytes.

Silica gel, functionalized, Propyl sulphonic acid, J.T.Baker®

Supplier: VWR Chemicals

Our silica wool is made from pure fused quartz fiber: amorphous, continuous, tangled, white, odorless, with no volatile component and no shot. Length, shape and arrangement of fibers give the wool its curly appearance preventing compression of the padding and improves its desired insulating properties.

Supplier: VWR Chemicals

This product adsorbs water vapour, so maintaining a dry environment for your products. When the gel's adsorption capacity is exhausted the colour changes from orange to colourless. The product can be regenerated back to an orange colour by heating in a drying oven at 120 to 140 °C for approximately 3 hours and then re-used. It is suitable for numerous drying applications, although it is not recommended for strongly acidic or strongly alkaline compounds.
