Silica Gel 400-700 Mesh For Column Chromatography

Product Description

Silica Gel 400–700 Mesh is an ultra-fine particle size grade of silica gel designed for specialized high-resolution column chromatography. With particle sizes ranging from ~20–38 µm, it provides superior separation efficiency, sharper resolution, and slower flow rates, making it particularly suitable for complex mixtures and closely related compounds.

This grade is primarily used in advanced pharmaceutical research, natural product isolation, biotechnology, and fine chemical purification, where maximum separation precision is required.
