Application Notes
Click here to learn the installation of a gas regulator
|
• Tube furnaces with quartz tubes are designed for using under vacuum and low pressure
< 0.2 bars / 3 psi / 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. - • Vacuum limit definition 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 - • Please click here to see our typical temperature profile calibration results at various temperatures.
- • In order obtain accurate temperature inside tube furnace, please click here to learn how to
calibrate the temperature on your own. - • How to set up tube and vacuum flange for MTI tube furnaces.
