An electrically heated furnace featuring a muffle—an inner chamber that isolates the workload from the heating elements and any potential contamination. Operating up to 1000°C or more, it provides a clean heating environment. The working principle allows for processes where sample purity is critical, such as analytical ash testing or sintering of sensitive powders. Its purpose is widespread in laboratories for material testing, heat treatment of small parts, and ignition tests. It is known for its temperature uniformity and protective atmosphere for samples.
This configuration is suitable when the sample load must fit a 450 x 450 x 900 MM chamber with usable chamber volume of 182.3 litre, approximate power load of 23.7 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.

Trutherm manufactures 1000 Degree Celsius (°C) Electric Muffle Furnace 450 x 450 x 900 MM Chamber for buyers who search by exact machine type, chamber size and 1000°C temperature rating. This page is specific to the MM dimension version, so the chamber size is presented in the unit normally used in the buyer's drawing, tender or purchase request.
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.
Because muffle furnaces are used across ashing, drying, calcination and light heat-treatment, the chamber and controller are specified for flexibility rather than one narrow process window.
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.
