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 690 × 345 × 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.

Routine QC and teaching labs value a muffle furnace precisely because one unit can cover several standard test methods without dedicated process-specific tooling.
Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
