A laboratory-scale muffle furnace designed for research, testing, and small sample processing. Capable of reaching 1000°C, it provides a clean, isolated heating environment. The working principle features a ceramic muffle tube or box that surrounds the sample, heated by external elements. Its purpose is for applications like determining ash content (LOI), heat treating small metal samples, sintering experimental ceramics, or conducting ignition tests where contamination from the furnace walls or elements must be avoided. It is a standard piece of equipment in analytical and materials labs.
Trutherm manufactures 1400 Degree Celsius (°C) Lab Muffle Furnace 575 x 575 x 850 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.
This configuration is suitable when the sample load must fit a 575 x 575 x 850 MM chamber with usable chamber volume of 281 litre, approximate power load of 28.3 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.

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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
