Analtech, Inc., is a manufacturer and distributer of precoated plates and equipment for sample preparation and Thin Layer Chromatography (TLC). Analtech developed the first commercially prepared TLC plates in 1961. These machine-made TLC plates, called UNIPLATES™, were significantly more uniform and reproducible then the best “homemade” plates produced in the classical manner. Since that time, Analtech has dedicated its resources to the improvement of TLC technology.
