Product Description
When it comes to reliable column chromatography, the right silica gel makes all the difference. This LR grade silica gel (100-200 mesh) from Avantor is specially designed for laboratory use, offering consistent particle size and high adsorption capacity. Whether you’re a student separating compounds in a university lab or a researcher purifying samples, this silica gel ensures sharp resolution and reproducible results.
Silica gel is a staple in chromatography because of its polar surface, which interacts effectively with a wide range of analytes. The 100-200 mesh size provides an optimal balance between flow rate and separation efficiency, making it ideal for both small-scale experiments and larger preparative work. Unlike finer meshes that can clog columns or coarser grades that compromise resolution, this mesh size delivers smooth elution without sacrificing performance.
What sets this product apart is its LR (Laboratory Reagent) grade, which guarantees low impurity levels and batch-to-batch consistency. You won’t have to worry about unexpected contaminants interfering with your results. Many researchers and educators trust eqipped for supplying authentic Avantor products, ensuring you get the same quality used in professional labs.
Using this silica gel is straightforward. Simply pack your column uniformly, ensuring no air bubbles, and let the solvent carry your sample through the stationary phase. The high surface area of silica gel allows for excellent separation of mixtures, whether you’re working with pigments, pharmaceuticals, or natural extracts. For best results, always pre-wet the silica gel with your chosen eluent before loading the sample.
If you’re new to column chromatography, here’s a quick tip: Always use a solvent system that matches your analyte’s polarity. Silica gel works best with non-polar to moderately polar solvents like hexane, ethyl acetate, or methanol. Avoid overly polar solvents that might compete too strongly with your sample for binding sites.
At eqipped, we understand that lab supplies need to be both high-quality and accessible. That’s why we offer this silica gel at competitive prices, with fast shipping across India. Whether you’re stocking up for a semester of experiments or need a reliable supply for ongoing research, you can count on us for products that meet rigorous standards.

FAQs
What is the difference between LR grade and AR grade silica gel?
LR (Laboratory Reagent) grade silica gel is suitable for most routine lab applications, including chromatography, and meets general purity standards. AR (Analytical Reagent) grade is higher purity, used when ultra-low impurities are critical, such as in quantitative analysis. For most chromatography needs, LR grade is sufficient and cost-effective.
Can I use this silica gel for flash chromatography?
While this silica gel can be used for flash chromatography, it’s not specifically optimized for high-pressure systems. For flash chromatography, consider silica gel labeled for that purpose, which typically has a narrower particle size distribution to handle higher flow rates.
How do I activate silica gel before use?
To activate silica gel, heat it in an oven at 105–110°C for 1–2 hours to remove adsorbed moisture. Allow it to cool in a desiccator before use. Avoid overheating, as this can alter its surface properties.
What solvents work best with this silica gel?
Non-polar to moderately polar solvents like hexane, chloroform, ethyl acetate, and methanol are commonly used. The choice depends on your sample’s polarity. Start with a less polar solvent and gradually increase polarity for gradient elution.
How much silica gel do I need for a column?
A common rule of thumb is to use 20–50 times the weight of your sample. For example, for 100 mg of sample, use 2–5 g of silica gel. The column diameter and height will depend on the scale of your separation.
