This is the formal name for a muffle furnace intended for laboratory use. Operating up to 1000°C or more, it is characterized by precise temperature control and uniformity. The working principle is identical to the Lab Muffle Furnace, with an emphasis on accuracy, reproducibility, and safety features suitable for a lab environment. Its purpose spans a wide range of scientific disciplines, from geology and chemistry to materials engineering, for sample preparation, thermal analysis, and small-scale processing under controlled conditions.
This configuration is suitable when the sample load must fit a 375 x 725 x 375 MM chamber with usable chamber volume of 102 litre, approximate power load of 18.7 kW, rectangular - tall 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 800 Degree Celsius (800°C) Laboratory Muffle Furnace 375 x 725 x 375 MM Chamber for buyers who search by exact machine type, chamber size and 800°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.
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.
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.
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.
