1600°C Max. Split Tube Furnace with Vacuum Flanges & Valves, Optional 60 or 80mm Alumina Tube - OTF-1600X-UL

0.0/5 rating (0 votes)



OTF-1600X-I series furnace is UL/TUV standard split-able alumina tube furnaces with Kanthal GLOBAR SG 1650 grade SiC Heating Elements. The furnace can install with 60 or 80mm O.D high-quality alumina tubes along with a pair of smart stainless steel vacuum sealing flanges that can take either a valve/gauge which allows for heating samples under vacuum or flowing gas conditions up to 1600°C. The precision temperature controller can provide 30 segments of heating and cooling steps with +/- 1°C accuracy.   SPECIFICATIONS

Application Notes

Click here to learn more about the installation of a gas regulator
  • The tube furnaces with alumina tube are designed for using under vacuum and low pressure < 0.02 MPa 
  • Never use graphite crucible an alumina tube.
  • Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit the-the pressure to below 3 PSI for safe operation. Click here to learn the installation of a gas regulator. 
  • Never heat the furnace while the gas release valve is closed and a positive pressure condition exists within the furnace chamber. The pressure gauge must be used to closely monitor the chamber condition at all times during the heating process; please open the gas release valve immediately once the chamber pressure has reached over 3 PSI to prevent unforeseeable damages.
  • .The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min )
  •  Vacuum pressures may only be safely used up to 1500°C
