Functionally identical to the Gem Heat Treatment Furnace, this unit thermally enhances gemstones. Operating around 600°C, its purpose is to diffuse impurities, heal fractures, or change color centers through controlled heating. The working principle requires extremely stable temperature control and often operates in batches. It is a key piece of capital equipment for gemstone wholesalers and treatment facilities, allowing them to consistently upgrade rough or low-grade gem material to meet market demands for color and clarity.
This configuration is suitable when the sample load must fit a 90 x 115 x 110 MM chamber with usable chamber volume of 1.1 litre, approximate power load of 3 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.

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.
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.
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.
