This furnace is used in analytical laboratories to determine the residue content of a material, often by burning off the non-residue portion. Operating at temperatures like 600°C, it facilitates controlled combustion. The working principle involves igniting a weighed sample and heating it until only inorganic ash remains, which is then weighed. Its purpose is to measure the inorganic (mineral) content of fuels, foodstuffs, polymers, and lubricants, providing important quality and compliance data for industries like petroleum, food processing, and plastics manufacturing.

Trutherm manufactures 1400 Degree Celsius (°C) Residue Analysis Furnace 625 x 315 x 315 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 625 x 315 x 315 MM chamber with usable chamber volume of 62 litre, approximate power load of 15.3 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.
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.
Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
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.
