Warning

Click here to learn the installation of a gas regulator

• The tube furnaces with quartz tube are designed for using under vacuum and low pressure <0.2 bar / 3 psi / 0.02 MPa
• 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: * Vacuum pressures may only be safely used up to 1000°C
