Product Overview
Silica gel, 100–200 mesh (LR grade), is a highly porous, granular form of silicon dioxide designed for column chromatography applications. Its uniform particle size distribution ensures consistent flow rates and high-resolution separations, making it ideal for laboratory purification processes. The 100–200 mesh range provides an optimal balance between surface area and flow resistance, enhancing separation efficiency. This LR-grade silica gel undergoes rigorous quality control to maintain purity and performance, ensuring reliable results in analytical and preparative chromatography. Its high adsorption capacity and chemical stability make it suitable for a wide range of organic and inorganic compounds. Store in a cool, dry place to prevent moisture absorption and maintain its effectiveness over time. Whether used in research or routine lab work, this silica gel delivers reproducible performance for critical separations.
FAQs
1. What is the ideal particle size for column chromatography?
For most column chromatography applications, a 100–200 mesh silica gel offers the best balance between flow rate and separation efficiency.
2. Can this silica gel be reused after activation?
Yes, it can be reactivated by heating at 120°C for 2–4 hours to remove absorbed moisture before reuse.
3. Is this silica gel compatible with acidic or basic solvents?
LR-grade silica gel is stable with most organic solvents but may degrade in strongly acidic or basic conditions.
4. How should I store unused silica gel?
Keep it in an airtight container with desiccant to prevent moisture absorption, which can reduce its efficiency.
5. What alternatives exist for faster separations?
Flash chromatography silica gel (230–400 mesh) provides finer particles for faster separations but may require higher pressure.
