General Description

100 Aluminium sheets 10 x 10 cmOur 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 100 size 10x10 cm for thin layer chromatography applications.
