Merck, 1168340001, TLC aluminum sheets, Silica gel 60 F₂₅₄

General description
50 Aluminium sheets 5 x 10 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 pensil 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 50 size 5x10 cm for thin layer chromatography applications.
