How to choose tube furnace and muffle furnace

When we apply, should we choose a muffle furnace or a tube furnace? Let's briefly talk about the difference between the two below.
1. The air tightness of the tube furnace is better. It is recommended to use the tube furnace for higher vacuum and air tightness requirements. Relatively speaking, the operation of the muffle furnace is relatively simple. In terms of temperature, both the tube furnace and the muffle furnace can reach 1800℃. The furnace size of the muffle furnace is controllable, and the test or production volume is larger. The diameter of the high-temperature tube furnace is limited, so the high-temperature tube furnace has a smaller volume than the high-temperature muffle furnace.
2. The tube furnace can control the calcination atmosphere. In addition, compared to the muffle furnace, the tube furnace in our laboratory can be heated at a higher temperature, can be programmed to control the temperature rise and fall, the temperature is more accurate, and the price is more expensive
3. If you want to calcinate samples with protective gas, you can use a tube furnace, and the tube furnace can also program the temperature, but if it is calcined in air, the calcining will be incomplete and it will not be in full contact with air.
Although some muffle furnaces can be programmed to increase temperature, they are not compatible with the gas, but the muffle furnace is the first choice if it is to be calcined in air. It is fully in contact with air and fully calcined.
