Application Notes & Warning
  • Tube furnaces with quartz tubes are designed for using under vacuum and low pressure < 0.2 bars / 3 psi / 0.02 MPa. Vacuum pressures may only be safely used up to 1000°CThe flow rate for gases should be limited to<200 SCCM (or 200ml/min) for reducing thermal shocks to the tube
  • 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.
  • How to set up a ceramic tube and vacuum flange for MTI tube furnaces.
  • For safety, you may consider putting the small tube furnace inside a fume hood. ( click picture left to see )
