Operating Precautions

1. Do not open the furnace chamber when its temperature is ≥300℃ to avoid injury.

2. During operation, tube pressure must not exceed 0.125MPa absolute to prevent damage from excessive pressure.

3. When operating under vacuum, the operating temperature must not exceed 800℃.

   4. Gas cylinders contain high pressure. A pressure-reducing valve must be fitted to the cylinder when supplying gas to the furnace tube. A low-pressure regulator with a range of 0.01MPa-0.15MPa is recommended for more precise and safer experimental use.

   5. When the furnace temperature exceeds 1000℃, the tube must not be under vacuum. Keep the tube at atmospheric pressure.

   6. The long-term operating temperature of the high-purity quartz tube is ≦1100℃.

   7. During heating experiments, closing both the exhaust and inlet valves at the tube flanges is not recommended. If the sample must be heated with the gas valves closed, continuously monitor the pressure gauge. If absolute pressure exceeds 0.15MPa, immediately open the exhaust valve to prevent accidents such as tube rupture or flange ejection.
