Product Overview
This indicating silica gel desiccant is a high-purity, ACS reagent-grade moisture absorber designed for critical applications requiring precise humidity control. The 6-18 mesh granular form ensures optimal surface area for maximum adsorption efficiency. The self-indicating property changes color from blue to pink as it saturates, providing a clear visual indicator of moisture absorption capacity. Manufactured under BAKER ANALYZED™ standards, this silica gel maintains consistent performance with minimal dust formation. The non-toxic, chemically inert composition makes it safe for use in sensitive environments. With a high adsorption capacity of up to 40% of its weight in water vapor, this desiccant effectively maintains dry conditions in sealed containers. The uniform particle size distribution ensures even moisture absorption throughout the packed material. This product meets ACS specifications for purity and performance, making it suitable for applications where reagent-grade quality is essential.
FAQs
1. How does the color change indicate saturation?
The blue crystals gradually turn pink as they absorb moisture, with complete color change indicating full saturation and need for replacement or regeneration.
2. Can this be regenerated after use?
Yes, saturated silica gel can be regenerated by heating at 120-150°C for 2-3 hours until the blue color returns, restoring its absorption capacity.
3. What is the difference between indicating and non-indicating silica gel?
Indicating silica gel contains cobalt chloride that changes color to show moisture saturation, while non-indicating remains colorless throughout its use.
4. Is this compatible with food storage applications?
While chemically inert, this ACS reagent grade is not specifically certified for direct food contact applications in India.
5. How should this be stored when not in use?
Keep in a tightly sealed container away from direct sunlight and moisture to maintain its absorption capacity and extend shelf life.
