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.

Avantor® Partisil® was one of the first commercially available irregular silicas. A large surface area gives it a high loading capacity. Avantor® Partisil® ion-exchange materials are widely referenced and remain one of the most popular choices for analysts.

Supplier: Merck

Desiccant suitable for desiccators to remove water, and for drying most gases and liquids (apart from strongly acidic and basic gases, organic solvents or alkaline liquids). The product contains iron salts as the indicator. Colour change is from orange to colourless at approx. 7/10 g adsorbed H₂O/100 g silica gel. Regeneration can be performed as often as required at 130 to 140 °C in a drying oven for approx. 3 hours.

Diatomaceous silica for filtration.

Supplier: Merck

Kieselguhr is a natural diatomaceous earth that can be used for the separation of polar or moderately polar compounds. For the mixed layer plates a combination of classical silica gel 60 and kieselguhr is used, providing favorable properties for certain applications such as separations of inorganic ions, herbicides or steroids.
