This furnace combines electric heating with a crucible container. Operating at temperatures such as 800°C, it provides a clean melting environment. The working principle uses electric elements to heat a crucible holding the charge, either from the outside or, in some lift-out designs, by lowering the crucible into a heated well. Its purpose is for small to medium batch melting of non-ferrous metals, alloys, and glass in settings like jewelry shops, dental labs, and R&D facilities, where controllability and cleanliness are prioritized.
This configuration is suitable when the sample load must fit a 250 x 350 x 750 MM chamber with usable chamber volume of 65.6 litre, approximate power load of 15.7 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.

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.
