Vacuum environment control: avoid oxidation and pollution, improve material purity
The high vacuum atmosphere tube furnace uses a vacuum pump to reduce the pressure inside the furnace to a very low level (usually 10 ⁻ Pa to 10 ⁻ ³ Pa), creating a low-pressure environment close to oxygen free. This feature effectively eliminates impurity gases such as oxygen and water vapor, providing a pure foundation for material processing. For example, in the sintering process of lithium-ion battery cathode materials (such as LiCoO ₂), a high vacuum environment can prevent cobalt oxidation and improve product capacity retention. In the field of semiconductor manufacturing, this equipment is used for CVD growth of materials such as gallium nitride (GaN). By controlling the ammonia flow rate and reaction chamber pressure, high-quality films with lower dislocation density can be prepared, and the growth rate can be improved.

Accurate atmosphere regulation: meeting the requirements of complex chemical reactions
The device supports multiple gas environments, including inert gases (such as argon and nitrogen), reducing gases (such as hydrogen), and reactive gases (such as oxygen and methane). Through the mass flow controller, the gas flow control accuracy is high, meeting the special requirements of different materials and processes for the atmosphere environment. For example, in metal heat treatment, introducing hydrogen gas can prevent metal oxidation; During the graphitization process of carbon materials, the introduction of methane can promote the ordered arrangement of carbon atoms and improve material properties. In addition, the device also supports complex atmosphere combinations, such as mixed gases of hydrogen and nitrogen, which can achieve simultaneous metal reduction and nitriding, simplifying the process flow.

High precision temperature control: ensuring the accuracy of experimental results
The high-altitude air atmosphere tube furnace adopts PID control algorithm, combined with high-precision thermocouples, to achieve temperature accuracy of ± 1 ℃. The device supports 30 segment programmable PID self-tuning technology, supports automatic heating and cooling, and meets complex experimental requirements. For example, in crystal growth experiments, precise temperature control can avoid crystal defects and improve crystal quality; In catalyst preparation, temperature fluctuations may affect catalyst activity, and high-precision temperature control can ensure stable catalyst performance.

Independent regulation of multiple temperature zones: adapting to complex process requirements
The device can achieve independent control of multiple temperature zones, and the temperature settings of each zone do not interfere with each other, meeting complex process requirements. For example, in the process of material synthesis, different parts may require different temperatures to achieve gradient structure and performance; In the heat treatment process, differentiated treatment can be carried out for different parts of the sample in different temperature zones to improve the treatment effect. The multi temperature zone design also improves equipment flexibility, allowing for multiple experiments to be conducted simultaneously and enhancing experimental efficiency.

Sample protection capability: reduce oxidation and pollution, improve material performance
Under vacuum and specific atmosphere, the high vacuum air atmosphere tube furnace effectively protects the sample from oxidation, contamination, and other effects. For example, in metal coating experiments, a vacuum environment helps to obtain a uniform and dense film layer; In the synthesis of nanomaterials, a vacuum environment can prevent nanoparticle aggregation and improve material purity. In addition, the device also supports rapid ventilation and exhaust functions, which can quickly eliminate impurities in the furnace and further protect the sample.

Highly customizable: meeting personalized needs
High fidelity air atmosphere tube furnace can be customized according to user needs, including furnace size, temperature range, heating method, atmosphere type and other parameters. For example, for large-sized samples, a longer furnace can be customized to meet experimental requirements; For high-temperature experiments, high-temperature resistant furnace materials (such as corundum tubes, quartz tubes) and heating elements (such as silicon molybdenum rods) can be selected; For special atmosphere requirements, gas pipelines and control systems can be customized. Customized services enable devices to better adapt to different experimental conditions and research directions, meeting personalized research needs.

Safe and reliable design: ensuring the safety of the experimental process
The equipment is equipped with multiple safety protection measures, such as over temperature protection, over voltage protection, leakage protection, gas leakage alarm, etc., to ensure the safety of the experimental process. For example, when the temperature inside the furnace exceeds the set value, the heating power supply will be automatically cut off to prevent equipment damage or experimental accidents; When the pressure inside the furnace exceeds the safe range, the pressure will be automatically released to avoid the furnace body from breaking; When the concentration of flammable or toxic gases exceeds the standard, an automatic alarm will be triggered and the gas source will be cut off. In addition, the device also adopts a double-layer water-cooled structure, effectively reducing the temperature of the shell and preventing burns.

Energy saving and environmental protection features: reduce operating costs and minimize environmental pollution
The high-altitude air atmosphere tube furnace adopts high-efficiency and energy-saving design, with high energy utilization rate and minimal impact on the environment. For example, the equipment uses good insulation materials (such as high-purity alumina fiber material) to reduce heat loss and energy consumption; Using high-temperature resistant heating elements (such as silicon carbon rods and silicon molybdenum rods) to improve heating efficiency; Support automatic recording and analysis of experimental data, optimize experimental parameters, and reduce energy waste. In addition, the equipment also supports gas recovery and recycling, reducing gas consumption and emissions.

Convenient operation: Simplify the experimental process and improve work efficiency
The device can be equipped with a touch screen or LCD display, which is intuitive and easy to operate. Users can display real-time parameters such as temperature, pressure, gas flow rate, etc., making it convenient for experimental monitoring and recording. Some models also support remote monitoring and operation, achieving unmanned operation during the experimental process. In addition, the equipment adopts a modular design, making it easy to replace heating elements, temperature sensors, gas pipelines, etc., and reducing maintenance costs.
