Temperature range:
Determine the temperature range of the furnace based on the high and low temperatures required for the experiment or production process.
For example, for high-temperature ceramic sintering, it may be necessary to choose a tube furnace that can reach 1800 ℃ or above; For general metal heat treatment, a tube furnace at around 1200 ℃ may be sufficient.

Vacuum requirement:
Consider the strictness of the process to the vacuum environment.
If semiconductor material preparation is to be carried out, ultra-high vacuum (<10 ^ -3 Pa) or above may be required; And for ordinary material processing, moderate vacuum (10 ^ -3-10 ^ -1 Pa) may be sufficient.

Furnace size:
Determine the diameter and length of the furnace based on the size and quantity of the samples.
If larger samples are frequently processed or multiple samples are processed simultaneously, a larger furnace space is required.

Heating element:
Common heating elements include resistance wires, silicon carbide rods, silicon molybdenum rods, etc.
Resistance wire has low cost but is relatively suitable for lower temperatures; Silicon carbon rods can withstand higher temperatures; Molybdenum wire is suitable for special high temperature and atmospheric conditions.

Control accuracy:
For processes that require high precision temperature control, such as precision alloy processing, it is necessary to choose a tube furnace with high-precision temperature control.

Cooling method:
A fast and effective cooling method can shorten the working cycle.
Water cooling is usually faster than air cooling, but it is necessary to consider whether there are corresponding water cooling facilities and conditions.

Automation level:
If frequent repetition of the same operation process is required, choosing a tube furnace with automated control function can improve work efficiency and accuracy.

Security:
Ensure that the tube furnace is equipped with safety devices such as over temperature protection, vacuum monitoring, and pressure protection to prevent accidents from occurring.

Brand and after-sales service:
Brands are usually more guaranteed in terms of quality and performance.
Good after-sales service can provide timely technical support and maintenance in case of equipment problems.

Budget:
Choose the appropriate model and configuration based on the budget.
Be careful not to sacrifice key performance and quality indicators just because of low prices.

In addition, the following factors can also be considered when making a purchase:
Heating rate: The speed of heating is related to whether the selection of thermocouples is reasonable and also reflects the quality of thermocouples.
Extreme vacuum degree and leakage rate: This is related to the sealing of the furnace and the relationship between the vacuum chamber and the heating rate.
Vacuuming time: Whether the time to reach the vacuum degree is too long is also a consideration when purchasing equipment.
Communication interface and data management: Equipped with communication interface and data management software, it can record historical data and temperature rise curves paperless, correct temperature deviation errors, and achieve remote fault diagnosis and analysis functions.
