Product Overview
Fuller’s Earth (China Clay) LR is a naturally occurring, highly adsorbent aluminum silicate mineral processed to laboratory reagent grade for precision applications. Its fine powder form ensures maximum surface area, making it exceptionally effective for adsorption, filtration, and decolorization processes in controlled lab environments. The LR grade guarantees minimal impurities, ensuring reliable and reproducible results in analytical and experimental procedures. Its unique mineral composition—primarily montmorillonite—provides superior binding capacity for organic compounds, oils, and pigments, while its inert nature prevents unwanted chemical reactions. This versatile clay is also widely used as a catalyst support in chemical synthesis due to its thermal stability and porous structure. The 500 g pack size offers convenience for frequent lab use without excessive storage concerns. Store in a cool, dry place in a tightly sealed container to maintain its adsorbent properties and prevent moisture absorption. Ideal for researchers and technicians requiring a consistent, high-performance adsorbent for critical laboratory workflows.
FAQs
1. What is the primary difference between Fuller’s Earth LR and commercial-grade clay?
Fuller’s Earth LR undergoes rigorous purification to meet laboratory reagent standards, ensuring minimal heavy metals, organic contaminants, and consistent particle size for reliable experimental outcomes. Commercial-grade clay lacks this precision and may contain impurities affecting results.
2. Can this be used for decolorizing liquid samples in chromatography?
Yes, its high adsorption capacity and fine particle distribution make it suitable for decolorizing organic solvents, oils, and biological extracts in preparative chromatography, though pre-testing with your specific sample is recommended.
3. How does storage humidity affect its performance?
Exposure to humidity reduces its adsorbent efficiency by occupying active sites with moisture. Always store in an airtight container with silica gel packets in high-humidity environments to preserve its properties.
4. Is this compatible with acidic or alkaline solutions?
Fuller’s Earth LR is stable in mildly acidic to neutral pH ranges (pH 5–8) but may degrade in strongly alkaline conditions (pH > 9). For acidic applications, verify compatibility with your specific solution to avoid leaching or structural breakdown.
5. What alternatives exist if Fuller’s Earth is unavailable?
Activated alumina or silica gel can substitute for adsorption tasks, though their selectivity differs. For decolorization, activated carbon is an option, but it may introduce particulate contaminants requiring additional filtration.
