105626 TLC Silica gel 60 50 Kaca pelat 10 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 pensil on the surface without risk to damage the layer.Suhu penyimpanan : tidak ada batasan.
