Chromatography Plates – TLC Polygram Plates 5 × 20cm (Pack of 50)

These TLC Polygram Chromatography Plates are high‑quality, general‑purpose thin layer chromatography (TLC) plates, designed for reliable and consistent separations in educational and laboratory settings. Pre‑coated with silica gel, the plates provide an excellent stationary phase for a wide range of qualitative and semi‑quantitative chromatography applications.

Each plate features a 0.25mm silica gel layer thickness with an average pore diameter of 6 µm, offering good resolution for separating mixtures such as dyes, inks, amino acids, and simple organic compounds. Measuring 5 × 20cm, these plates are ideal for classroom demonstrations and student practical work. Supplied without a UV indicator, they are suitable for visualisation techniques using coloured compounds or chemical staining.

Supplied as a pack of 50, these chromatography plates are well suited to busy school and college laboratories, supporting repeated use across multiple lessons and practical sessions.
