What is the temperature of tube furnaces used in university laboratories?

The temperature range of tube furnaces used in university laboratories is relatively wide, depending on experimental requirements and equipment specifications. Generally speaking, the temperature range of a tube furnace can range from a few hundred degrees Celsius to as high as 1700 ℃ or higher. Here are some common temperature ranges and their application scenarios:

Low temperature tube furnace:
Temperature range: usually below 500 ℃.
Application scenario: Suitable for experiments that do not require high temperature, such as drying of biological samples, low-temperature synthesis, etc.
Medium temperature tube furnace:
Temperature range: generally between 500 ℃ and 1200 ℃.
Application scenario: Suitable for heat treatment of most conventional materials, such as annealing, sintering, ashing, etc.
High temperature tube furnace:
Temperature range: above 1200 ℃, some equipment can reach 1700 ℃ or higher.
Application scenarios: Suitable for the synthesis of high-temperature materials, high-temperature sintering of metals or ceramics, chemical analysis (such as high-temperature decomposition), etc.
Specifically, some common types of tube furnaces and their temperature ranges are as follows:

1100 ℃ high-temperature tube furnace: The maximum working temperature can reach 1100 ℃, and the continuous working temperature is stable at 1000 ℃.
1200 ℃ single temperature zone/double temperature zone/triple temperature zone tube furnace: providing different temperature zone configurations, with a maximum temperature of up to 1200 ℃.
1400 degree three temperature zone vacuum atmosphere university laboratory tube furnace: with a three temperature zone design, the highest temperature can reach 1400 ℃, suitable for the synthesis and heat treatment experiments of complex materials.
1700 ℃ single temperature zone/double temperature zone/triple temperature zone tube furnace: provides a higher temperature range, with a maximum temperature of 1700 ℃, suitable for the preparation and research of high-temperature materials.
It should be noted that although the maximum temperature of the tube furnace is an important indicator, in practical use, the recommended working temperature is usually 100 ℃ to 150 ℃ lower than the maximum temperature to extend the service life of the equipment and ensure the accuracy of the experiment. In addition, when choosing a tube furnace, factors such as the type of heating element, temperature control accuracy, heating rate, and furnace material need to be considered to meet specific experimental requirements.
