Chromatography Plates – 4 × 8 cm, Pack of 50 (Silica Gel, TLC, No UV Indicator)

These TLC ‘Polygram’ Chromatography Plates measure 4 × 8 cm and come pre‑coated with silica gel, making them ideal for a wide variety of thin‑layer chromatography separations. With an average pore diameter of 6 nm and a layer thickness of 0.25 mm, these plates offer reliable, consistent performance across most general‑purpose TLC applications.

Supplied in a pack of 50, they are perfect for routine classroom experiments, qualitative analysis, and advanced chromatography investigations. These plates are supplied without a UV indicator, making them suitable for dye, pigment, and chemical separations that do not require UV detection.
