Multi-Zone Tube Furnace

The tube furnace is split with two, three or five heating zones, which can achieve faster heating up to 1200℃ and create a different thermal gradient by adjust different heating zone temperature. It is excellent furnace to prepare functional materials under thermal gradient, epitaxial film growth by CVD or PVD with a vacuum system, and also can be used for annealing, diffusing and sintering sample in various atmospheres
