This designation refers to a furnace engineered to reach very high temperatures, typically above 1000°C, with many capable of 1200°C to 1800°C. It is a category rather than a specific application. The working principle employs special refractory linings and high-temperature heating elements like silicon carbide, molybdenum disilicide, or tungsten. Its purpose is for processes requiring extreme heat: sintering advanced ceramics, melting refractory metals, high-temperature testing, and glass research. It is essential for advanced materials development and processing.
This configuration is suitable when the sample load must fit a 645 x 330 x 330 MM chamber with usable chamber volume of 70.2 litre, approximate power load of 16.1 kW, rectangular - wide 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 Temp Furnace 645 x 330 x 330 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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
