About IChromatography Silica Gel Gf 20X20Cm Uniplate-T
The UNIPLATE-T Taper Plate, invented and patented by Analtech, is a unique preparative TLC plate that provides unusually high resolution for a preparative layer. It has a wedge-shaped adsorbent layer, progressing from 300 microns (bottom) to 1700 microns (top.) Below the silica layer is a 700-micron-thick preadsorbent zone provided for easier sample application and higher sample resolution. Sample concentration prior to separation occurs in this preadsorbent zone. The tapered adsorbent layer causes low Rf bands to separate further than on a preparative plate of constant thickness. A more uniform developing solvent flow pattern reduces vertical band spreading. All of these factors combine to produce extraordinary resolution in preparative separations on the UNIPLATE-T Taper Plate. For additional information regarding the UNIPLATE-T Taper Plate request Analtechnology Report No. 8202. Minimized band distortion at higher Rf values Resolution better than on some analytical plates Increased separation at low Rf values
