S-HL, VertiPlate™ Organic Hard-layer TLC are plates the most rugged silica gel plates available. They not only ease handling and sample application, but also permit the use of up to 80% water in the developing solvent without loss of adherence of the adsorbent layer to the glass plate. Organic binder plates are recommended for all TLC applications except those that use vigorous charring for visualization. Virtually all other visualization methods are free from interference from the organic binder. Special high performance silica gel with 10?m particle size result in separations 25% to 30% faster than with most other TLC plates.

     Prescored plates are an economical alternative to having many different size plates. Prescored 20x20cm plate has 3 score markes 5cm apart. Plates can be easily snapped apart to provide four 5x20cm plates. Prescored 10x20cm plate provides four 2.5x10cm plates. Prechanneled plates help prevent cross contamination by separating multiple samples. More sample can be separated on a plate and the spot zones can be determined more readility. Prechanneled 20x20cm plates have 19 channels. Prechanneled 10x20cm plates have 9 channels. Prechanneled 5x10cm plates have 4 channels.

     Preadsorbent plates have a nonadsorbent layer at the bottom of the plate. This band of innert material reshapes and concentrates the spots into narrow bands which improve separation. It allows the loading of large volumes of sample without loss of resolution
