Operating Principle

The Multi-Zone Tube Furnace operates by precisely heating a sample placed within a tube in a highly controlled environment. The furnace comprises multiple heating zones, each equipped with its own heating elements and thermocouple, controlled independently by the PID system. This allows for the creation of specific temperature gradients along the length of the tube or a highly uniform temperature zone. Samples can be processed under vacuum (achieved via an external vacuum pump connected to the sealed flanges) or in a controlled atmosphere by flowing specific gases through the tube.
