Product Description
Silica Gel GF254 is a high-purity silica gel specifically designed for Thin Layer Chromatography (TLC) applications. It is composed of silica gel with calcium sulfate binder (G) and an added fluorescent indicator (F254) that enables visualization of separated compounds under UV light at 254 nm.
Widely used in pharmaceutical, chemical, and academic laboratories, Silica Gel GF254 is ideal for qualitative and semi-quantitative analysis of complex mixtures, ensuring sharp separations and reproducible Rf values.
