Silica Gel G For Thin Layer Chromatography

Product Description

Silica Gel G is a specialized grade of silica gel designed specifically for Thin Layer Chromatography (TLC). It is a fine, high-purity silica gel powder blended with a small percentage of calcium sulfate (CaSO₄) as a binder, ensuring strong adhesion to glass, plastic, or aluminum plates when used as a coating.

Silica Gel G is the most widely used adsorbent in TLC due to its excellent separation capacity, uniform layer formation, and reproducibility. It enables qualitative and semi-quantitative analysis of mixtures in laboratories, academic research, and pharmaceutical industries.
