• Tube furnaces with alumina tubes are designed for use under vacuum and low pressure < 0.12 atm (absolute pressure)
• The flow rate for gases should be limited to < 200 SCCM for reducing thermal shocks to the tube
• Attention: A two-stage pressure regulator must be installed on 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: up to 1000°
