Product Overview

Silica Gel Self-Indicating 6-20 mesh Blue (CAS No. 112926-00-8) is an amorphous porous silica desiccant supplied in the specified 6-20 mesh particle range with an incorporated moisture-responsive blue indicator system. Water is adsorbed on the extensive silanol-bearing internal surface, while progressive hydration is accompanied by a visual indicator response. The mesh designation defines the submitted particle-size classification without requiring conversion to an unprovided numerical diameter range.

The self-indicating 6-20 mesh form is intended for laboratory drying and humidity-control applications requiring relatively coarse, easily contained particles and visual assessment of desiccant condition. Its particle form is suitable for packed beds, drying columns and enclosed desiccant compartments where dust minimisation and practical handling are important.

Typical Applications

• Desiccant beds for laboratory gas or enclosed-air drying systems.
• Moisture control in desiccators, cabinets and storage enclosures.
• Visual indication of progressive desiccant moisture loading.
• Drying cartridges and packed containers designed for coarse silica gel.
• Protection of moisture-sensitive laboratory materials and equipment.
• Laboratory humidity-control and desiccant-performance studies.

Common Synonyms

• 6-20 mesh indicating silica gel
• Blue indicating silica gel
• Self-indicating silica gel
• Amorphous silica gel
• Silica gel

Storage Conditions

Store unused material in a tightly sealed container protected from ambient humidity to preserve adsorption capacity and initial indicator response. Avoid contamination by liquids, oils, dust or volatile materials that could occupy adsorption sites or obscure colour changes.
