TLC Silica gel 60 F254, EMD Millipore Sigma
TLC Silica gel 60 F254
Glass TLC plate, silica gel coated with flourescent indicator F254. The silica gel TLC plates come in a quantity of 25 size 20 x 20cm for Thin Layer Chromatography applications. This classical silica TLC plates are based on a combination of our proven silica gel 60 and the addition of a unique polymeric binder resulting in a very adherent and hard surface that will not crack or blister and even allow writing with a pencil on the surface without risk to damage the layer.
