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.

Trutherm manufactures 1400 Degree Celsius (°C) Electric Crucible Furnace 230 x 170 x 240 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.
This configuration is suitable when the sample load must fit a 230 x 170 x 240 MM chamber with usable chamber volume of 9.4 litre, approximate power load of 7.1 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.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
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.
