Product Description
Silica Gel 200–400 Mesh is a fine-particle, high-resolution grade silica gel specifically designed for special column chromatography applications. With a particle size range of ~38–74 µm, this grade provides excellent separation efficiency, sharper resolution, and slower flow rates, making it ideal for complex compound purification and high-precision chromatographic techniques.
It is widely used in pharmaceutical research, natural product isolation, biotechnology, and advanced organic synthesis where maximum separation accuracy is required.
