Classic TLC silica plates, GF254 (Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 Å pore size. Aluminum backed-easily cut by a pair of scissors.
Precut size of 2.5cm by 7.5cm, 80 plates per box.
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.
Actual examples performed with the plates have been uploaded for users to see.
Easily Cut ：Silica gel GF254， It contains both calcined gypsum and fluorescent agent. Diameter of 60 Å，It can be used to observe fluorescence under ultraviolet light with a wavelength of 254. The aluminum back can be easily cut open with scissors.
Good separation effect: The spots are small and convenient for series analysis. The separation time is short, and more than 5 groups can be separated per minute.
High sensitivity: The spots are clear, no spreading and no trailing. Large separation capacity. It’s suitable for thin layer scanning quantitative analysis.
