설명

일반 설명

200 Glass plates 5 x 10 cm

Our classical silica TLC plates are based on a combination of proven our 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 pensil on the surface without risk to damage the layer.

애플리케이션

Glass TLC plate, silica gel coated with flourescent indicator F254. The silica gel TLC plates come in a quantity of 200 size 5x10 cm for thin layer chromatography applications.
