OTF-1200X-S-50-LVT high-temperature vacuum tube furnace is a split tube furnace for heating samples up to 1200°C. KF25 Gas Outlet and Digital Vacuum Gauge on the right flange connecting a 156L/m Mechanical Pump and Pump Filter while 1/4'' barb gas inlet on the left, allows the furnace to heat the sample in vacuum up to 1E-2 Torr or flowing gas. In addition, a OMEGA 1/4’’ O.D K Type Thermocouple comes to the left flange, which can be inserted inside the tube to exactly measure the sample’s temperature by the readout from the OMEGA Calibrator. The precision temperature controller will provide 30 segments of heating and cooling steps with +/- 1 °C accuracy.

Application Notes


  • Tube furnaces with quartz tubes are designed for using 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 limit for all quartz tube furnaces: Vacuum pressures may only be safely used up to 1000°C
  • The flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
  • How to set up a ceramic tube and vacuum flange for MTI tube furnaces.
  • For safety, the small tube furnace can be placed inside a fume hood. ( click the picture left to see )
Certificate
  • NRTLs or CSA certification is available at extra cost.
