This small furnace is used in metallography labs to heat treat small samples of metal for subsequent microscopic examination. Operating at temperatures around 600°C, it allows for controlled annealing, hardening, or aging. The working principle provides uniform heating to small specimens to create specific microstructures (like martensite or spheroidized cementite) that can then be polished, etched, and analyzed. Its purpose is research and failure analysis, helping metallurgists understand how processing history affects a material's microstructure and, consequently, its properties.

Trutherm manufactures 1200 Degree Celsius (°C) Metallographic Sample Furnace 150 x 150 x 300 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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 150 x 150 x 300 MM chamber with usable chamber volume of 6.8 litre, approximate power load of 6.2 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 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.
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.
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.
