Precautions for using the equipment

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

2. During equipment use, the pressure inside the furnace tube must not exceed 0.125MPa (absolute pressure) to prevent excessive pressure from damaging the equipment; 3. When using under vacuum, the equipment operating temperature must not exceed 800°C; 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 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 during use; 5. When the furnace body temperature exceeds 1000°C, 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 operating temperature of high-purity quartz tubes is ≤1100°C; 7. During heating experiments, it is not recommended to close the exhaust valve and the inlet valve at the flange end of the furnace tube. If it is necessary to close the gas valve to heat the sample, 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).
