A general term for any furnace designed to operate at elevated temperatures, typically above 1200°C. This distinguishes it from standard furnaces that max out at lower ranges. The working principle involves advanced materials science in its construction—special refractories, heating elements, and thermocouples—to withstand thermal stress and oxidation. Its purpose is for research, development, and production in fields like materials science, metallurgy, and chemistry, where processes are pushed to thermal limits to create new compounds or properties.
Trutherm manufactures 1200 Degree Celsius (°C) High-Temperature Furnace 765 x 400 x 400 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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.
This configuration is suitable when the sample load must fit a 765 x 400 x 400 MM chamber with usable chamber volume of 122.4 litre, approximate power load of 20.2 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.

Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
Where sample volume and process type vary week to week, a general-purpose muffle furnace avoids the cost of maintaining several process-specific furnace types.
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.
