Descripción

Descripción general

25 Glass plates 20 x 10 cm for AMD acc. to DIN 38407-F11

HPTLC Plates AMD with extra thin layer of only 100 µm have been specially developed for even more demanding application such as automated multiple development (AMD). It combines the repeatedly development of the plate in the same direction and reproducible gradient elution. AMD development provides extremely narrow bands, allowing the complete resolution of to 40 components on 60 mm distance.
