Product Description
When precision matters in your chromatography work, the right silica gel makes all the difference. This silica gel for TLC (230-400 mesh) from CDH is engineered for consistent, high-resolution separations in thin-layer chromatography. Whether you’re a student learning the basics or a researcher refining complex mixtures, this grade delivers the clarity and reliability your experiments demand.
The 230-400 mesh particle size strikes the perfect balance between flow rate and separation efficiency. Finer than standard silica but coarse enough to avoid clogging, it ensures smooth solvent migration while maintaining sharp spot resolution. This makes it ideal for both qualitative analysis and preparative TLC applications.
What sets this silica gel apart is its rigorous quality control. Each batch undergoes strict testing to guarantee uniform particle distribution, minimal impurities, and consistent performance. You’ll notice fewer streaks, cleaner baselines, and more reproducible Rf values—critical factors when your research depends on accurate data.
At eqipped, we understand that lab supplies should be as reliable as your methodology. That’s why we source this silica gel directly from trusted manufacturers, ensuring you receive a product that meets international chromatography standards. Whether you’re separating plant extracts, pharmaceutical compounds, or synthetic intermediates, this TLC grade silica gel provides the foundation for trustworthy results.

Why This Silica Gel Stands Out
The market offers many silica gel options, but not all deliver the same performance. This 230-400 mesh variant excels in several key areas:
First, its tightly controlled particle size distribution eliminates the variability that plagues lower-quality alternatives. You won’t waste time troubleshooting uneven plates or inconsistent solvent fronts. The uniform mesh size also means you can standardize your protocols across different experiments, saving valuable lab time.
Second, the high surface area (typically 500-600 m²/g) provides ample binding sites for your analytes. This translates to better separation of closely related compounds—something particularly valuable when working with complex natural product extracts or reaction mixtures.
Finally, the chromatography-grade purity means fewer interfering peaks in your results. While industrial-grade silica might contain metal impurities that cause tailing or ghost spots, this TLC-specific grade is processed to remove such contaminants. Your UV or staining results will be cleaner, making interpretation more straightforward.
Practical Applications in Your Lab
This silica gel isn’t just for textbook TLC demonstrations. Researchers across India rely on it for real-world applications:
Pharmaceutical labs use it to monitor reaction progress and verify compound purity during synthesis. The consistent separation allows chemists to quickly identify side products or unreacted starting materials.
In natural product research, it helps isolate bioactive compounds from plant extracts. The fine mesh size is particularly effective at separating structurally similar flavonoids or alkaloids that might co-elute on coarser media.
Educational institutions appreciate its reliability for student practicals. When demonstrating chromatography principles, instructors need materials that work predictably every time—this silica gel delivers that consistency.
Quality control laboratories in food and cosmetic industries also employ it for detecting adulterants or verifying ingredient profiles. The high resolution helps identify even trace components that might affect product quality.
Getting the Best Results
To maximize performance with this silica gel, consider these practical tips:
For plate preparation, use a consistent slurry concentration (typically 1:2 silica:water ratio) and spread evenly with a plate coater. Uneven layers can cause solvent front distortion.
Activate your plates properly—110°C for 30 minutes is standard—but adjust based on your compound’s sensitivity. Over-activation can lead to irreversible adsorption of some analytes.
When developing your chromatogram, choose solvents appropriate for your compound’s polarity. The uniform particle size of this silica gel makes it responsive to even small changes in solvent composition, allowing fine-tuning of separations.
For visualization, while UV is common, don’t overlook chemical staining. The pure silica matrix provides a clean background that enhances spot visibility with reagents like ninhydrin or iodine.
Safety and Handling
While silica gel is generally safe, proper lab practices should always be followed. Wear appropriate PPE when handling the fine powder to avoid inhalation. The material is non-toxic but can be irritating to respiratory tracts if airborne particles are inhaled.
Store in a cool, dry place in tightly sealed containers. Silica gel is hygroscopic and will absorb moisture from the air, which can compromise its chromatographic performance. The original packaging from eqipped is designed to maintain product integrity during storage.
Dispose of used silica gel according to your institution’s chemical waste protocols. While not hazardous, contaminated silica from chromatography applications may require special handling depending on the solvents used.
FAQs
What makes 230-400 mesh silica gel ideal for TLC?
The 230-400 mesh size offers the perfect balance between resolution and flow rate. Smaller particles provide better separation but can slow solvent migration, while larger particles allow faster flow but poorer resolution. This intermediate size delivers both sharp separations and reasonable development times.
Can I use this silica gel for column chromatography?
While primarily designed for TLC, this grade can be used for flash chromatography with appropriate adjustments. For standard column work, you might prefer larger particle sizes (60-200 mesh) for better flow rates. However, many researchers successfully adapt this TLC grade for small-scale preparative separations.
How should I store unused silica gel?
Keep it in its original airtight container at room temperature. For long-term storage, consider adding desiccant packs to the container. Always reseal the bag immediately after use to prevent moisture absorption, which can degrade performance.
What’s the typical loading capacity for this silica gel?
For analytical TLC, loading capacity is usually 1-5 µg per spot for most compounds. For preparative work, you can scale up to 10-50 mg per 20×20 cm plate, depending on the complexity of your mixture and the separation required.
Does eqipped offer bulk discounts on this silica gel?
Yes, we provide competitive pricing on larger quantities. The 25 kg option offers excellent value for high-volume users. Contact our customer service team to discuss your specific requirements and potential bulk pricing for research institutions or commercial labs.
