1. Clear usage requirements
Working temperature range: Determine the required working temperature range based on production requirements. For example, if the working temperature is below 1000 ℃, a metal tube furnace such as stainless steel can be chosen, which has low cost and durable furnace tubes; If the working temperature is below 1200 ° C, the furnace tube can be selected as a quartz tube, and the heating element is a tube furnace containing molybdenum resistance wire; If the working temperature is between 1200 ° C and 1400 ° C, a tubular furnace with alumina tubes and silicon carbon rods as heating elements can be selected; If the temperature is higher, it may be necessary to choose higher-level heating elements and furnace tube materials.
Atmosphere requirements: Determine whether a vacuum or specific atmosphere environment is needed to select the appropriate type of tube furnace, such as a vacuum tube furnace or an atmosphere tube furnace.
Heating rate: Select a tube furnace with the corresponding heating rate according to the production requirements for heating rate.
Sample size: Select the appropriate furnace tube diameter and length based on the sample size that needs to be heated. Large diameter production type tube furnaces should be able to accommodate larger samples or process multiple samples in batches.
High requirements for uniform heating: If the requirements for uniform heating are relatively high, a rotating inclined tube furnace can be selected. This tube furnace can ensure uniform heating of materials, and some models can also be designed for continuous feeding and discharging, saving labor costs.

2. Consider technical parameters
Furnace tube material: The furnace tube material should be able to withstand the required working temperature and have good chemical stability. Common furnace tube materials include metal tubes, quartz, alumina, corundum ceramics, etc.
Heating element: The selection of heating elements should be based on the operating temperature range and heating rate requirements. Common heating elements include molybdenum containing resistance wires, silicon carbon rods, silicon molybdenum rods, etc.
Temperature control system: Choose a tube furnace with a high-precision temperature control system to ensure the accuracy and stability of temperature control. The temperature control system should be able to achieve multi-stage programming to meet the needs of different process stages.
Temperature uniformity: Ensure that the tube furnace has excellent temperature uniformity to ensure uniform heating of the sample and improve product quality.

3. Pay attention to security performance
Safety protection measures: Choose a tubular furnace with necessary safety protection measures, such as over temperature protection, over-current protection, and trip protection, to ensure the safe operation of the equipment.
Safety certification: Refer to the product's safety certification certificate or testing report to ensure that the product complies with relevant safety standards.

4. Consider the convenience of operation
Operation interface: Choose a tube furnace with a user-friendly operation interface and good control system to improve work efficiency and reduce operational difficulty.
Automation level: Select a tube furnace with appropriate automation level according to production needs, such as automatic sampling, automatic temperature control, automatic recording, etc.

5. Evaluate after-sales service
Brand reputation: Choose a brand with good reputation and service to ensure product quality and after-sales service.
After sales service policy: Understand the manufacturer's after-sales service policy, including warranty period, repair service, parts supply, etc., in order to receive timely technical support and repair service during use.

6. Consider cost-effectiveness
Equipment price: Compare the prices of different models and choose the product with higher cost-effectiveness while meeting the usage requirements and technical parameters.
Operating costs: Consider the long-term operating costs of the equipment, such as energy consumption, maintenance costs, etc., in order to choose an economically efficient tube furnace.
