TLC Silica gel 60

半岛bd体育手机客户端 说明

一般描述

100 Glass plates 2.5 x 7.5 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.
