Chromatography Plates – TLC Polygram 20 × 20cm (Pack of 25)

These TLC Polygram Chromatography Plates are high‑quality, general‑purpose thin layer chromatography (TLC) plates, ideal for reliable separations in teaching and laboratory environments. Pre‑coated with silica gel, they provide a consistent and effective stationary phase suitable for a wide range of chromatography investigations.

Each plate features a uniform 0.25mm silica gel layer thickness with an average pore diameter of 6 µm, offering dependable resolution for the separation of mixtures such as inks, dyes, pigments, amino acids, and other organic compounds. The larger 20 × 20cm format allows multiple samples to be run simultaneously, making these plates particularly suitable for structured classroom practicals.

Supplied without a UV indicator, these plates are ideal for experiments where separation results can be visualised directly by colour or through chemical staining methods. Provided as a pack of 25, they offer excellent value for schools and colleges delivering regular chromatography lessons.
