• NRTL or CSA certification is available upon request at extra cost.

Warning  

Click here to learn the installation of a gas regulator

• Tube furnaces with quartz tubes are designed for use under vacuum and at low-pressure < 0.2 bars 
• Attention: A two-stage pressure regulator must be installed on the gas cylinder to limit the pressure to below 3 PSI for safe operation.
• A maximum temperature of 1000°C should be imposed on all quartz tube furnaces to avoid the quartz tubes undergoing deformations under vacuum.
• The flow rate for gasses should be limited to < 200 SCCM for reducing thermal shocks
