General Description

50 Plastic sheets 4 x 8 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

Plastic TLC plate, silica gel coated with flourescent indicator F254. The silica gel TLC plates come in a quantity of 50 size 4x8 cm for thin layer chromatography applications.
