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.
This configuration is suitable when the sample load must fit a 900 x 875 x 875 MM chamber with usable chamber volume of 689.1 litre, approximate power load of 40.7 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) Lab Muffle Furnace 900 x 875 x 875 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.
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.
