Application Notes

• The internal pressure of the quartz tube must not exceed 0.02 MPa.
• A pressure regulator must be installed on the cylinder before introducing gas into the quartz tube.
  • For safety, it is recommended to use a pressure below 0.02 MPa.
  • We recommend purchasing a MTI pressure regulator , which has a range of 0.01 MPa – 0.1 MPa, ensuring greater accuracy and safety.
• For sample heating experiments, it is not recommended to operate with both the exhaust valve and gas inlet valve on the furnace tube flange closed.
  • If gas valves must be closed during sample heating, the pressure gauge reading must be monitored at all times.
  • If the pressure exceeds 0.02 MPa, the release valve must be opened immediately to prevent potential hazards such as quartz tube rupture or flange detachment.
• We do not recommend using flammable, explosive, or toxic gases.
  • If the process requires the use of such gases, customers must take appropriate protective and explosion-proof measures.
  • Our company is not responsible for any issues arising from the use of flammable, explosive, or toxic gases.
