|
• The tube furnaces with quartz tube 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°C.
The flow rate for gasses 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.
