Descripción

General description

Irregular-shaped Silica gel with narrow, well defined particle size distribution delivering high separating performance, permeability and good reproducibility

Features and Benefits

Silica gel 60 (35-70 µm)provides users with:

• High adsorptive capacity
• High chemical inertness and non-toxicity.
• Protective moisture-sensitive substances during storage and transport or for maintaining the dryness of anhydrous solvents.
• Granulates in different sizes or beads

Packaging

Plastic bottle
