STF Models are heated by SiC elements, which run parallel to the work tube. Optional tubes with a maximum outer diameter of 90 mm can be used. SiC heated tube furnaces can also be used vertically; other options are also available. A digital PID controller is integrated into the furnace.
The CTF models are heated with MoSi2 heating elements, which are suspended vertically down each side of a horizontal tube. A Eurotherm 3216 P1 programmer with 8 segment pairs and an adjustable overtemperature controller are fitted as standard. Optional work tubes up to 90 mm outer diameter can be used.
