TLC plates, unmodified silica gel 60
Merck silica gel 60 has a unique polymeric binder that results in a uniform, hard surface that will not easily crack or blister. This smooth, extremely dense plate coating ensures narrow bands and maximum separation efficiency with the lowest background noise. Layer thickness 250 μm and particle size of 10 to 12 µm. Two inorganic fluorescent indicators for UV detection of colourless substances.

TLC plates, concentrating zone
These plates are based on different adsorption properties of two silica adsorbents: An inert large pore concentrating adsorbent where the samples are applied, and a selective layer for the separation. Independent of the shape, size or position of the spots, the sample always concentrates within seconds as a narrow band at the interface of the two adsorbents, where the separation begins. Quick and easy sample application. Includes a purification and concentration step.

GLP plates
Laser-coded GLP plates that are individually marked with item, batch and individual plate number. Based on the same proven Merck silica gel 60, these GLP plates perform exactly as corresponding TLC or HPTLC plates.
