A muffle furnace designed to operate at the upper limits of muffle technology, typically 1200°C or higher. The working principle uses a high-grade ceramic muffle (often alumina) and silicon carbide heating elements capable of withstanding these temperatures while still providing a clean environment. Its purpose is for high-temperature ash testing, sintering of advanced powders, or heat treatment of materials where contamination from elements or insulation must be prevented. It is a premium tool for demanding laboratory applications.
This configuration is suitable when the sample load must fit a 490 x 490 x 890 MM chamber with usable chamber volume of 213.7 litre, approximate power load of 25.3 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 1400 Degree Celsius (°C) High Temperature Muffle Furnace 490 x 490 x 890 MM Chamber for buyers who search by exact machine type, chamber size and 1400°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.
