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 1000 Degree Celsius (1000°C) Residue Analysis Furnace 345 × 580 × 345 MM Chamber for buyers who search by exact machine type, chamber size and 1000°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 345 × 580 × 345 MM chamber with usable chamber volume of 69 litre, approximate power load of 16 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.
