TLC Plates 120/box Plastic Backed Silica Gel 60 F254 2.5cm x 6.5cm Precut Size AAdvance Instruments

Features

• Classic TLC silica plates, GF254 (Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 angstroms pore size. Plastic 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.

Description

1. Classic TLC silica plates, GF254 (Silica gel with gypsum as binding agent, fluorescence background at 254nm), 60 angstroms pore size. Plastic backed- easily cut by a pair of scissors. The partially transparent plastic allows viewing of compound spots from the back side after staining. 2. Precut size of 2.5cm by 6.5cm, 120 plates per box. 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. 3. 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. 4. Actual examples performed with the plates have been uploaded for users to see.
