• The tube furnaces with alumina tubes are designed for use under vacuum and low pressure < 0.02 MPa
• 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.
• The flow rate for gasses should be limited to < 200 SCCM ( or 200ml/min )
•  Vacuum pressures may only be safely used up to 1500°C
