Silica gel 60, irregular 40 - 63 µm for flash chromatography

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.
