Designed for melting and processing precious metals like gold, silver, and platinum, this furnace features digital control for accuracy. Operating at high temperatures (e.g., 1100°C), it ensures precise thermal management of valuable materials. The working principle often involves induction or resistance melting in a crucible, with digital settings to achieve the exact melting point and superheat needed for casting. Its purpose is to provide jewelers, refiners, and dental labs with a reliable, efficient tool that maximizes metal yield and consistency while minimizing oxidation loss.
This configuration is suitable when the sample load must fit a 880 x 520 x 520 MM chamber with usable chamber volume of 238 litre, approximate power load of 26.4 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.

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.
