Temperature range:
Determine the required operating temperature range based on experimental or production needs. Pay attention to the maximum temperature that the instrument can maintain (for short-term use) and the temperature at which the instrument can operate continuously (for safe, long-term use).
Understand the types and limitations of heating elements, such as resistance wire heating elements, which are typically suitable for a temperature range of 200-1200 ℃.
Furnace tube and crucible:
Choose the appropriate furnace tube diameter and crucible based on the size and type of the sample. Ensure that the crucible can withstand the experimental temperature and is compatible with the furnace tube.
Quartz crucibles are suitable for lower temperatures (≤ 1200 ℃), while alumina crucibles are suitable for higher temperatures (≤ 1800 ℃).
Vacuum pumping and atmospheric circulation function:
Confirm that the tube furnace has a reliable vacuum pumping system and the ability to introduce atmospheres such as inert gases, reducing gases, etc.
Check the performance and pumping rate of the vacuum pump, as well as the stability and accuracy of the atmosphere control system.
Structure and Operation:
Consider whether the structure of the furnace body is convenient for sample collection, placement, and observation. For example, an open door structure can provide a more convenient operating experience.
Evaluate the usability and functionality of the control system, including temperature control, atmosphere control, safety alarms, etc.
Brand and after-sales service:
Choose common brands of tube furnaces, which typically have more mature technology and more reliable after-sales service.
Understand the warranty period and maintenance services of the equipment, as well as the technical support and training provided by the manufacturer.
Price and cost-effectiveness:
Choose a cost-effective tube furnace based on the budget range. Be careful to avoid the trap of false information caused by excessively low prices.
Taking into account factors such as equipment performance, brand, and after-sales service, choose the most suitable equipment.
Safety and Environmental Protection:
Ensure that the tube furnace complies with relevant safety standards and environmental requirements.
Check whether the equipment has safety functions such as overheating protection and short circuit protection.
