VertiPlate™ HPTLC plates with unbonded-silca are available with Organic Hard-layer binder and Inorganic hard-layer binder.

     HPS-HL, Organic Hard-layer binder HPTLC plates have little effect on the separation characteristics of the sorbent but most durable silica gel plates. These plates allow use of 80% water in the solvent system. They are used to avoid the problems of binder interference but cannot be used for visualization.

     HPS-GH, Inorganic Hard-layer binder HPTLC plates have little effect on the separation characteristics of the sorbent but it does make the layer hard and abrasive resistant. These plates allow use of 100% water in the solvent system. They are used when strong acid charring is used for visualization or when the presence of an organic binder interacts with the solvent system.

     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 eight 2.5x10cm plates.

     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.
