Vacuum furnace: graphite furnace
Inductotherm
In graphite heating, maintaining the desired temperature profile within the susceptor is absolutely critical in order to achieve maximum productivity. Precise power input to each zone of the susceptor is achieved by varying either or both the overall power level and the amount of time power is switched to a particular zone of the coil during each power distribution cycle of the system. This leads to increased yields of product over a given length hot zone
