Product Overview
This BAKER ANALYZED™ silica gel (80-200 mesh) is a high-purity, granular adsorbent designed for demanding laboratory applications. The controlled particle size distribution ensures consistent performance in column chromatography, thin-layer chromatography (TLC), and other separation techniques. With a large surface area and uniform pore structure, this reagent-grade silica gel delivers superior adsorption capacity for moisture, organic compounds, and impurities. Its chemically inert nature prevents unwanted reactions, making it suitable for sensitive analytical procedures. The material undergoes rigorous quality testing to meet strict reagent-grade specifications, ensuring batch-to-batch consistency. The 80-200 mesh range provides an optimal balance between flow rate and resolution, while the high surface area (typically 500-800 m²/g) enables efficient separation of complex mixtures. This silica gel maintains structural integrity under various solvent conditions and can be easily regenerated through thermal treatment. Its low metal content and neutral pH make it particularly valuable for applications requiring minimal interference. The product comes in a 500g pack size, offering sufficient quantity for routine laboratory use while maintaining freshness through proper packaging.
FAQs
1. What is the ideal moisture content for this silica gel before use?
This silica gel typically contains 5-7% moisture when packaged. For most applications, it can be used as-is, but for critical chromatography, activation at 105-110°C for 2-3 hours is recommended to achieve optimal dryness.
2. How does the 80-200 mesh size compare to other mesh ranges for chromatography?
The 80-200 mesh range offers a balance between flow rate and resolution. Finer meshes (200-400) provide better resolution but slower flow, while coarser meshes (30-70) allow faster flow with reduced separation efficiency. This range is ideal for general-purpose chromatography.
3. Can this silica gel be reused after initial application?
Yes, this silica gel can be regenerated by heating at 150-180°C for 4-6 hours to remove adsorbed materials. Cool in a desiccator before reuse. Note that repeated regeneration may slightly reduce adsorption capacity over time.
4. What solvents are compatible with this BAKER ANALYZED™ silica gel?
This silica gel is compatible with most organic solvents including hexane, ethyl acetate, methanol, and dichloromethane. Avoid strongly basic or acidic solvents that may degrade the silica structure. Always test compatibility for your specific application.
5. How should this silica gel be stored to maintain its properties?
Store in a tightly sealed container in a cool, dry place away from direct sunlight and moisture. Keep the original packaging until use to prevent contamination. Once opened, transfer to an airtight container with desiccant if not used immediately.
