TLC Plates
Sorbent Technologies Inc C18-W Silica TLC Plates, w/UV254, glass backed, 250um, 20x20cm, 25/pk
This thin layer chromatography (TLC) plate comprises a C18-W (Wettable) Silica layer. It can be used in both normal phase or reversed phase separations with eluents from anhydrous solvents to mixtures with high concentrations of water. The relative polarity of the eluent determines the polarity of the layer. The Silica 60 has a surface area of 500 m2/g, mean pore size of 60A, specific pore volume of 0.75 ml/g, particle size of 2-10um, and pH stability of 2-10. The TLC plates contain UV254 fluorescent indicator. The UV-absorbing substances appear as dark-blue to black spots on a light - blue background. This analytical layer is bound to a glass support. It has a thickness of 250um and dimensions of 20x20cm. There are 25 plates per pack. Applications include: aminophenols, barbiturates, preservatives, nucleobases, polycyclic aromatic hydrocarbons, steroids, tetracyclines, plasticizers (phthalates)
Biotage TLC Plates, 5cm x 10 cm Glass, with silica, 50 per cas
Biotage TLC plates are the perfect tool to predict flash methods for Biotage Sfar columns. For synthetic chemists, the benefits of matched TLC plates and flash cartridges are better purification throughput, increased compound purity and yield, and reduced solvent cost.These glass plates are coated with silica and are 5cm x 10cm packed 50 plates to a case.
