TLC plates, unmodified silica gel 60
This range of plates uses Merck silica gel 60 with a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. The smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 200 μm and, particle size of 10 to 12 µm. Flexible aluminium plates that can easily be cut to match individual separation requirements. Two inorganic fluorescent indicators for UV detection of colourless substances. Samples which absorb shortwave UV at 254 nm are detected due to fluorescence quenching.
