| Precautions for Use | ·The air pressure in the quartz tube should not be higher than 0.02MPa (relative air pressure). · Due to the high air pressure inside the gas cylinder, a pressure reducing valve must be installed on the gas cylinder when introducing gas into the quartz tube. In order to ensure safety, it is recommended to use a pressure lower than 0.02MPa. It is recommended to purchase a pressure reducing valve from our company. The range of the company's pressure reducing valve is 0.01MPa-0.1MPa, which will be more accurate and safe when used. · For sample heating experiments, it is not recommended to close the exhaust valve and intake valve at the flange end of the furnace pipe. If you need to close the valve to heat the sample, you need to pay attention to the number of pressure gauges at all times. If the number of pressure gauges is greater than 0.02MPa, the vent valve must be opened immediately to prevent accidents (such as broken furnace pipes, flanges flying out, etc.) · We do not recommend that customers use flammable, explosive and toxic gases. If the customer does need to use flammable, explosive and toxic gases for technical reasons, please take relevant protective and explosion-proof measures by yourself. The company is not responsible for related problems caused by the use of flammable, explosive and toxic gases. |
| Compliance | CE Certified, UL or CSA certification is available at extra cost. |
Temperature uniformity calibration method of dual zone split tube furnace:
1. Prepare for adaptation equipment: choose 3 to 5 K-type thermocouples that have been metered and certified, and arrange them evenly according to the length of the heating zone of the dual zone split tube furnace. The thermocouple probes should be fixed on the quartz sample boat and placed in the center and both ends of the two zones to avoid contact with the inner wall of the furnace tube.
2. Set the calibration parameters: set the target temperature of the open type vacuum tube furnace to the commonly used operating temperature, and the heating rate is set according to daily experiments. After reaching the target temperature, keep warm for 60 minutes to stabilize the temperature in the furnace.
3. Data recording and analysis: through the temperature control system of the two zone split tube furnace or an external data recorder, the temperature data of each thermocouple is recorded in real time, recorded every 5 minutes, and the average value is calculated from the data of the last 30 minutes of the insulation stage. The temperature difference between the points in a single zone should be ≤±5℃.
4. Adjustment and optimization: if the temperature uniformity of a certain zone is not up to standard, you can adjust the power distribution knob of the corresponding heating zone of the two zone split tube furnace, or check whether the heating wire is loose, repeat the calibration process until it meets the standard, and keep the data archived after calibration.
