Warning
Click here to learn more about the installation of a gas regulator.
|
- The tube furnaces with alumina tube are designed for use under vacuum and low pressure < 0.02 MPa / 0.2 Bar/ 3 PSI
- Attention: A two-stage pressure regulator must be installed on a gas cylinder to limit 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 )
- limit definition for all alumina tube furnaces: * Vacuum pressures may only be safely used up to 1500°C
