Light polymerization units are for polymerization of light curig materials, e.a. Megatray light curing tray material, Megaseal UNIVERSAL sealing lacquer and other light curing materials in the UVA area. The units are also with blue light lamps (spectrum 400-500 nm) available upon request. Megalight ST is an ideal unit for the use in dental technical laboratory. With 4 fluorescence lamps is an optimal light polymerization effect obtained. The large polymerization room makes the simultaneous curing up to 4 models possible.
