General description
25 Aluminium sheets 20 x 20 cm
Our 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.
Application
Aluminum TLC plate, silica gel coated with flourescent indicator F254. The silica gel TLC plates come in a quantity of 25 size 20x20 cm for thin layer chromatography applications.
