8 Zone Split Tube Furnace For Thermal Gradient Processing upto 1500C - OTF-1500X-Z8

0.0/5 rating (0 votes)


OTF-1500X-Z8  is an eight-zone tube furnace with a mullite tube and conventional flange working up to 1500°C.. Each SiC heating element is controlled by an independent temperature controller to create the various thermal gradient for special processing in material research, such as gradient functional material, high-through phase transition and re-crystallization, etc.

Application Notes
  • The tube furnaces with mullite tubes are designed for use under vacuum and low pressure < 0.02 Mpa
  • Never use graphite crucible in alumina tube.
  • AttentionA two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.  Please click here to learn the installation of a gas regulator. 
  • The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min )
  •  Vacuum pressures may only be safely used up to 1300°C
Dimensions Furnace only: 35" × 23" × 30"
