This is a digitally controlled furnace specifically for glass-related processes like melting, fusing, slumping, or annealing. Operating at temperatures such as 800°C, it allows artisans to program intricate thermal cycles. The working principle combines robust heating elements suitable for glass with a digital controller that can manage critical phases like the annealing soak and controlled cool-down to prevent stress and breakage. Its purpose is to provide glass artists and studios with reliable, reproducible results for creating fused glass artwork, kiln-formed glass, and scientific glassware.
This configuration is suitable when the sample load must fit a 770 x 400 x 400 MM chamber with usable chamber volume of 123.2 litre, approximate power load of 20.2 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.

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.
