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 500 x 140 x 250 MM chamber with usable chamber volume of 17.5 litre, approximate power load of 9.2 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 1100 Degree Celsius (°C) Electric Crucible Furnace 500 x 140 x 250 MM Chamber for buyers who search by exact machine type, chamber size and 1100°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.
