基本信息
| General description【一般描述】 | 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 pencil on the surface without risk to damage the layer. 25 Plastic sheets 20 x 20 cm |
