Maximum temperature of graphite furnace vacuum furnace

The maximum temperature of a graphite furnace vacuum furnace can usually reach 2200 ℃, and some high-end models can even operate stably at 2300 ℃ or higher. Let’s take a detailed look below!

temperature range
Conventional models: The design maximum temperature of most graphite furnace vacuum furnaces is between 2000 ℃ and 2200 ℃. For example, some models have a rated temperature of 2000 ℃, with a long-term operating temperature of up to 1800 ℃, and a maximum temperature of 2200 ℃.
High end models: Some high-end graphite furnace vacuum furnaces use special materials and designs, allowing their maximum temperature to exceed 2200 ℃.

influencing factors
Heating element: The heating element of graphite furnace vacuum furnace is usually made of high-purity graphite, and its high temperature resistance directly determines the maximum temperature of the furnace.
Furnace material: In addition to the heating elements, other parts of the furnace (such as insulation materials, feeding platforms, etc.) also need to be made of high-temperature resistant materials to ensure the stability and safety of the entire furnace at high temperatures.
Vacuum system: The performance of the vacuum system also has a significant impact on the temperature distribution and heating effect of the furnace. An efficient vacuum system can ensure the vacuum level inside the furnace, thereby reducing heat loss and improving heating efficiency.
Control system: A good control system can better control the heating temperature and vacuum degree, ensuring the stability and reliability of the furnace at high temperatures.Click to learn more Vacuum Furnaces! Or click on online customer service to learn more about product information!
