The Story

OTF-1100X-III series is a three-zone split tube furnace with optional 11" or 15" OD quartz tubes and hermetic flanges. The furnace features a pair of motorized actuator to open and close the furnace lid in an ease. Three programmable PID temperature controllers allows a smooth heating and cooling ramps with a fluctuation less than 1ºC. It has been widely used for materials synthesis, wafer annealing, diffusion, and heat treatment for bulk sample under vacuum or gas atmosphere.
