Classic TLC silica plates, GF254 (Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 angstroms pore size. Aluminum backed-easily cut by a pair of scissors.
Precut size of 2.5cm by 6.5cm, 120 plates/box. 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 cpds. with an amino group even without adding triethylamine. At the same time non-amino cpds. behave the same as on acidic TLC plates.
Actual examples performed with the plates have been uploaded for users to see. In listing photo 5, 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.
