When choosing a vacuum tube furnace for laboratory use, multiple factors need to be considered to ensure that the selected equipment can meet the experimental requirements. Let's take a detailed look at what to pay attention to when choosing a vacuum tube furnace for laboratory use!

Temperature range:
Determine based on the highest and lowest temperatures required for the experiment or production process. For example, high-temperature ceramic sintering may require a tube furnace capable of reaching temperatures above 1800 ℃, while general metal heat treatment may only require equipment at around 1200 ℃.
Vacuum requirement:
Consider the strictness of the process to the vacuum environment. Different applications may require different levels of vacuum, such as semiconductor material preparation requiring ultra-high vacuum (<10 ^ -4 Pa), while ordinary material processing may require moderate vacuum (10 ^ -3~10 ^ -1 Pa) to meet.
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; Silicon molybdenum rods are suitable for special high temperature and atmospheric conditions. The selection should be based on the working temperature and budget.
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 the laboratory has 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. Meanwhile, 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 actual budget. However, it should be noted that key performance and quality indicators cannot be sacrificed solely for low prices.
So, when choosing a vacuum tube furnace for laboratory use, it is necessary to comprehensively consider multiple factors such as temperature range, vacuum requirements, furnace size, heating elements, control accuracy, cooling method, automation level, safety, brand and after-sales service, and budget. By carefully evaluating these factors, it can be ensured that the selected equipment can meet the specific needs of the laboratory.Click to learn more tube furnaces!
