Description

Silica Gel is a highly porous, amorphous form of silicon dioxide, widely recognized for its exceptional adsorption capacity. This property makes it an indispensable desiccant and adsorbent for controlling moisture and protecting products from degradation. It is a critical material for industries requiring precise humidity control, including pharmaceuticals, food packaging, electronics, and industrial gas processing. Silica Gel CAS NO 112926-00-8 is available in various mesh sizes and grades to meet specific application requirements.

Application

• Desiccant in Packaging: Protects sensitive goods such as electronics, pharmaceuticals, leather goods, and optical instruments from moisture damage during storage and shipment.
• Adsorption in Chromatography: Used as a stationary phase in column chromatography for the separation and purification of chemical compounds.
• Catalyst Carrier: Serves as a high-surface-area support material for catalysts in various chemical synthesis and petrochemical processes.
• Air & Gas Drying: Effectively removes water vapor from compressed air, natural gas, and other industrial gas streams.
• Food Preservation: Maintains dryness and crispness in packaged food products to extend shelf life.
• Laboratory Use: Employed in desiccators to create a dry atmosphere for storing moisture-sensitive chemicals and samples.

Quality Control

Our Silica Gel is manufactured under a stringent quality management system. Each batch is tested against rigorous specifications for parameters such as adsorption capacity, pore size distribution, pH, and loss on drying. We can provide material compliant with relevant industrial and technical grades. A Certificate of Analysis (COA) is available for every shipment to ensure traceability and quality assurance.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic nature, the container must be kept sealed in a cool, dry place when not in use to prevent premature moisture uptake and maintain adsorption efficacy. Standard storage temperature is 15-25°C.
