Vendeur: aadvanceinstrumentsllc ✉️ (548) 100%, Lieu où se trouve: Stony Brook, New York, US, Lieu de livraison: US et de nombreux autres pays, Numéro de l'objet: 323280994256 Plaques de silice TLC 120 plaques/boîte support aluminium GF254 2,5 x 6,5 cm taille précoupée . Classic TLC silica plates, GF254 (Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 Å pore size. When was the last time you needed a full sheet of TLC? Maybe you never did. With precut strips at a highly affordable price, save precious research time and labor, and focus more on the cutting-edge aspects of your research. What's ideal is that these plates have neutral silica (pH 6-7) instead of the more common acidic silica (pH=5) for TLC silica plates. The neutral silica make the plates compatible with running compounds with an amino group even without the need of adding triethylamine. At the same time non-amino compounds behave the same as on acidic TLC plates.

In listing photo 5 (or below), highly similar diethyl maleate and dimethyl maleate are spotted on the plates and eluted with different ratios of ethyl acetate : hexanes, showing a gradual change of Rf.

120 plates per box, 2.5 cm x 6.5 cm size.
