Product Details

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 sinteri sample in various atmospheres
