Furnaces
Muffle furnaces are used in the lab for high-temperature applications involving testing of various materials. The ability of these furnaces to achieve extremely high temperatures is integral for many critical industrial applications. By definition, a muffle furnace (also sometimes referred to as a retort furnace) isolates the subject material from the fuel and all of the products of combustion, including gases and flying ash. The units are usually front-loading, box-type construction that are placed or mounted on a benchtop in a testing laboratory.
Typical applications include:
- Research and analysis of material properties by reducing the materials to absolute ashes.
- Heat treatment for metallurgical processes to make structural changes in the materials at the molecular level.
- Aerospace industries utilize them to test the flame retardancy of aircraft parts at extremely high temperatures.
Humboldt provides benchtop muffle furnaces in three sizes/configurations. All are equipped with ceramic fiber insulation for faster heating and reduced energy consumption. They also feature an embedded heating element on the top and both sides for temperature uniformity.
