A compact, portable furnace designed to sit on a laboratory bench or workshop table. Operating up to 600°C or more, it provides a small, efficient heating chamber. The working principle is a scaled-down version of larger chamber furnaces, with electric heating elements and basic or digital controls. Its purpose is for small-scale heat treatment, ashing, preheating, curing, and educational demonstrations where space is limited or only small samples are processed. It is popular in school labs, jewelry benches, and for R&D prototyping.

Trutherm manufactures 1200 Degree Celsius (°C) Tabletop Furnace 490 x 875 x 490 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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 490 x 875 x 490 MM chamber with usable chamber volume of 210.1 litre, approximate power load of 25.1 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.
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.
