1. Clarify experimental requirements
Temperature range: determined based on the highest temperature and temperature stability required for the experiment. Different CVD processes may require different temperature ranges, so it is important to ensure that the selected electric furnace can meet these requirements.
Atmosphere control: CVD processes typically require specific atmospheres, such as inert gases, reducing gases, or oxidizing gases. Therefore, it is necessary to choose an electric furnace that can precisely control the atmosphere.
Heating method: The common heating method is usually resistance heating.
Furnace size: The furnace size should be large enough to accommodate the experimental sample and ensure that the sample can be uniformly heated during the heating process.

2. Assess equipment performance
Temperature uniformity: Temperature uniformity is an important indicator for evaluating the performance of CVD electric furnaces. To ensure uniform temperature distribution inside the furnace, in order to avoid experimental results deviation caused by uneven heating of the experimental samples.
Heating rate: The heating rate determines the time required for the experiment. Rapid heating can shorten the experimental period, but it may also have an impact on the experimental results. Therefore, the appropriate heating rate should be selected according to the experimental requirements.
Cooling system: Cooling system is important for protecting equipment and ensuring experimental safety. Choose an electric furnace with a reliable cooling system to ensure stable operation of the equipment during the experiment.

3. Consider equipment reliability and maintainability
Equipment quality: Choose good brands and suppliers with a good reputation to ensure the quality and reliability of the equipment.
After sales service: Understand the supplier’s after-sales service policies, including equipment warranty period, maintenance services, and technical support. This will help solve potential issues that may arise during the use of the device.
Maintenance cost: Consider the maintenance cost of the equipment, including the cost of replacing vulnerable parts, repair costs, etc. Choosing equipment with lower maintenance costs can reduce experimental costs.

4. Refer to user reviews and market feedback
User evaluation: Check the user’s evaluation of the selected device to understand the actual usage effect and existing problems of the device. This helps to have a more comprehensive understanding of the performance and quality of the equipment.
Market feedback: Understand the price, performance, and user feedback of similar devices in the market in order to make more informed decisions.

5. On site investigation and trial use
Whenever possible, conduct on-site inspections of the supplier’s production environment and equipment production line to understand the production process and quality control procedures of the equipment.
