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 1200 Degree Celsius (°C) Lab Muffle Furnace 200 x 200 x 300 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 200 x 200 x 300 MM chamber with usable chamber volume of 12 litre, approximate power load of 7.9 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.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
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.
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.
