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

These TLC Polygram Chromatography Plates with UV Indicator are high‑quality, general‑purpose thin layer chromatography (TLC) plates, designed for accurate and reliable separations in educational and laboratory environments. Pre‑coated with silica gel, they provide an effective stationary phase suitable for a wide range of analytical and teaching applications.

Each plate features a uniform 0.25mm silica gel layer thickness with an average pore diameter of 6 µm, delivering consistent separation performance. The integrated UV indicator allows colourless compounds to be easily visualised under UV light, making these plates ideal for more advanced chromatography investigations. The larger 20 × 20cm format provides ample working area for multiple samples or comparative studies.

Supplied as a pack of 25, these plates are well suited to repeated use in GCSE and A‑Level chemistry laboratories, supporting practical lessons and exam‑focused investigations.
