OTF-1200X-VI-2M-UL is a Six-zone & ultra-long split tube furnace with separated temperature control units and max working temperature of 1200oC. This six-zone furnace can create a step thermal gradient or 60" ( 1500mm ) long constant heating zone by setting all the temperature controllers at the same temperature. The furnace can accept processing tubes with various O.D (1" to 4") at extra cost. Six 30-segment temperature controllers are built in a separate control box which allows PC software control of the furnace from a certain distance. It is an excellent furnace to handle various gases.

 Application Notes
Warning
  • Tube furnaces with quartz/mullite tubes are designed for use under vacuum and low pressure <0.2 bar
  • Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator.
  • * Vacuum pressures may only be safely used up to 1500°C  
  • The flow rate for gases should be limited to<200 SCCM for reducing thermal shocks to the tube
