TLC Silica gel 60 F₂₅₄

半岛bd体育手机客户端 说明

一般描述

500 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.

应用

Glass TLC plate, silica gel coated with flourescent indicator F254. The silica gel TLC plates come in a quantity of 500 size 2.5x7.5 cm for thin layer chromatography applications.
