1. Temperature requirements
Maximum temperature: Select the appropriate temperature range for the heating furnace based on the maximum temperature required for the experiment. For example, some experiments may require high temperatures of 1200 ℃, 1400 ℃, or even 1700 ℃.
Continuous operating temperature: In addition to the maximum temperature, it is also necessary to consider the temperature range within which the instrument can operate continuously to ensure the safety and stability of the experiment.
Heating element: Different heating elements are suitable for different temperature ranges. For example, resistance wire heating elements are suitable for lower temperature ranges, while silicon carbon rods or silicon molybdenum rods are suitable for higher temperature ranges.

2. Sample size
Crucible selection: Choose a suitable crucible based on the size and properties of the sample. For example, quartz crucibles are suitable for lower temperature ranges, while corundum crucibles are suitable for higher temperature ranges.
Furnace tube diameter: After selecting the crucible, choose the appropriate furnace tube diameter based on the volume of the crucible loaded with the sample.

3. Number of temperature zones
Multi temperature zone requirement: The multi temperature zone tubular sintering furnace can control the temperature difference at different positions, which is suitable for experiments that require complex temperature gradients.
Selection of Temperature Zones: Choose the appropriate number of temperature zones according to the experimental requirements. For example, tube furnaces with dual temperature zones, triple temperature zones, or more temperature zones can meet different experimental needs.

4. Functional requirements
Atmosphere control: If the experiment needs to be conducted in a specific atmosphere (such as nitrogen, argon, hydrogen, etc.), a tube furnace with atmosphere control function needs to be selected.
Vacuum function: For experiments that require a vacuum environment, a tube furnace with vacuum function should be selected.
Rapid temperature rise and fall: If the experiment requires rapid temperature rise and fall to improve efficiency, a tube furnace with rapid temperature rise and fall function should be selected.

5. Structural type
Horizontal and vertical: There are two structural types of multi temperature zone tube sintering furnaces: horizontal and vertical. Horizontal tube furnace is the most common type, while vertical tube furnace is mostly used for material settling experiments, gas volatilization experiments, fluidized bed experiments, etc.
Special structure: According to experimental requirements, tube furnaces with special structures can also be selected, such as rotating tube type, automatic feeding and discharging type, multi station type, etc.

6. Brand and after-sales service
Brand selection: Choose a well-known brand's multi temperature zone tubular sintering furnace to ensure product quality and after-sales service.
After sales service: Understand the manufacturer's after-sales service policy, including repair, maintenance, technical training, etc., to ensure timely resolution of problems encountered during the experimental process.
