This furnace is specifically designed to evaluate the high-temperature oxidation or corrosion resistance of materials. Operating up to 1000°C or higher, it subjects samples to controlled oxidizing atmospheres. The working principle involves precise control of gas composition (air, oxygen, or mixed gases) and temperature while periodically measuring the sample's weight change or examining its surface. Its purpose is to screen and qualify materials like superalloys, coatings, and ceramics for use in aggressive environments, such as in chemical processing plants, power generation, and aerospace applications.
This configuration is suitable when the sample load must fit a 390 x 390 x 770 MM chamber with usable chamber volume of 117.1 litre, approximate power load of 19.8 kW, square chamber profile. It is commonly selected for laboratory, QC, metallurgical, ceramic, pharmaceutical and industrial heat-treatment work requiring stable heating and repeatable process conditions. Typical use includes general laboratory and industrial heat-treatment applications requiring stable, repeatable temperature control.

A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
A muffle furnace isolates the sample from direct contact with heating elements or combustion gases, giving cleaner, more repeatable results than an open flame or hot-plate process.
As a general-purpose muffle furnace, this model covers a broader range of routine heating tasks than a process-specific ashing, tube or sintering furnace, making it the practical default when the lab runs mixed sample types rather than one dedicated process.
