Precautions for using the equipment

1. When the furnace temperature of the equipment is ≥300℃, it is prohibited to open the furnace to avoid injury;

2. During the use of the equipment, the pressure inside the furnace tube must not exceed 0.125MPa (absolute pressure) to prevent excessive pressure from damaging the equipment; 3. When used under vacuum, the operating temperature of the equipment must not exceed 800℃. 4. The internal pressure of the gas cylinder is relatively high. When introducing gas into the furnace tube, a pressure reducing valve must be installed on the gas cylinder. It is recommended to purchase a small pressure reducing valve for experimental use, with a range of 0.01MPa-0.15MPa, which will be more precise and safe when in use. 5. When the furnace body temperature is higher than 1000℃, the furnace tube must not be in a vacuum state; the pressure inside the furnace tube should be equivalent to atmospheric pressure, maintaining a normal pressure state; 6. The long-term use temperature of high-purity quartz tubes should be ≤1100℃ 7. During heating experiments, it is not recommended to close the exhaust valve and inlet valve at the flange end of the furnace tube. If it is necessary to heat the sample with the gas valves closed, the pressure gauge reading must be monitored at all times. If the absolute pressure gauge reading exceeds 0.15MPa, the exhaust valve must be immediately opened to prevent accidents (such as furnace tube rupture or flange flying out).
