Radial development on HPTLC plates increases separation of low Rf spots and gives better resolution than with linear development. Circular development provides a rapid means of analyzing single samples or for scouting solvent conditions in methods development. The Analtech Radial/Circular Developing System is designed for the development of radial and circular chromatograms on 10 x 10 cm HPTLC plates. The Radial/Circular Developing System includes the chamber, the base with solvent reservior, two clamps, the spotting guide, 500 wicks of each type, and complete instructions.
