Application Notes
  • The tube furnaces with mullite tube are designed for using under vacuum and low pressure < 0.02 Mpa / 0.2 Bar/ 3 PSI 
  • Never use graphite crucible in alumina 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. Please click here to learn the installation of a gas regulator. 
  • The flow rate for gases should be limited to < 200 SCCM ( or 200ml/min )
  • Vacuum limit definition for all mullite tube furnaces: * Vacuum pressures may only be safely used up to 1300°C
Dimensions Furnace only: 35" × 23" × 30"
