Product SKU: qPN7643fda
Moisture Indicator: Silica Gel Blue is a moisture-indicating desiccant that changes color from blue to pink as it absorbs moisture, indicating saturation.
Composition: It is a porous, granular form of silicon dioxide (SiO₂) with cobalt chloride as the moisture indicator, which gives it its blue color.
High Adsorption Capacity: Known for its ability to adsorb water vapor effectively, it can absorb up to 40% of its weight in moisture.
Regenerable: Silica Gel Blue can be regenerated and reused by heating it to remove the absorbed moisture, typically at 120°C - 150°C.
Granule Size: It is available in different granule sizes, usually ranging from 1 to 5 mm, tailored to specific applications.
Toxicity Concern: Contains cobalt chloride, a toxic substance, which limits its use in direct contact with food, pharmaceuticals, or other consumable products.
Moisture Control in Packaging: Commonly used to protect electronics, machinery, and other sensitive items from moisture damage during storage and transportation.
Humidity Indicator: Employed in environments where humidity monitoring is crucial, such as in museums, libraries, and art galleries, to protect valuable items.
Industrial Applications: Used in compressed air systems, air dryers, and gas purification processes to control moisture and prevent corrosion.
Laboratory Use: Utilized in laboratories for drying and storing sensitive chemicals and reagents that require moisture-free environments.
Optical Instruments Protection: Helps in keeping optical instruments like cameras, telescopes, and lenses free from fogging and moisture damage.
Medical Equipment: Used in medical device packaging to maintain a dry environment, protecting equipment from moisture-related degradation.
Toxicity: Avoid direct contact with food, pharmaceuticals, or other consumables due to the presence of cobalt chloride, which is toxic.
Handling: Handle with care, using gloves and masks to avoid inhalation or skin contact with cobalt chloride, which can be harmful.
Disposal: Dispose of used Silica Gel Blue according to local regulations for hazardous materials, as it contains toxic substances.
Regeneration Safety: When regenerating, ensure proper ventilation and avoid overheating, as excessive heat can degrade the silica gel or release harmful fumes.
Color Change Monitoring: Regularly monitor the color change to pink, indicating saturation, and replace or regenerate the silica gel to maintain effectiveness.
Environmental Concerns: Consider using alternative desiccants without cobalt chloride if environmental or health safety is a concern, especially in consumer products.
