A furnace used in the field of metallography for preparing metal samples for microscopic analysis. Operating at temperatures like 600°C, it is used for processes like stress relieving after cutting or inducing specific phase transformations. The working principle is similar to a small laboratory box furnace, with an emphasis on temperature uniformity across small samples. Its purpose is to simulate heat treatment conditions on a lab scale or to prepare standardized samples for comparison, providing a direct link between thermal processing and the resulting microstructure seen under the microscope.
This configuration is suitable when the sample load must fit a 250 x 140 x 250 MM chamber with usable chamber volume of 8.8 litre, approximate power load of 6.9 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) Metallography Furnace 250 x 140 x 250 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.
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.
