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.
Trutherm manufactures 800 Degree Celsius (800°C) Laboratory Muffle Furnace 435 × 435 × 825 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.
This configuration is suitable when the sample load must fit a 435 × 435 × 825 MM chamber with usable chamber volume of 156.1 litre, approximate power load of 22.3 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.

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.
