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.
Trutherm manufactures 800 Degree Celsius (°C) Metallography Furnace 390 x 750 x 390 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 390 x 750 x 390 MM chamber with usable chamber volume of 114.1 litre, approximate power load of 19.6 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.

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.
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.
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.
