Synonymous with the LOI Furnace, this unit is designed for the standardized test method of measuring the mass loss of a sample upon heating. Operating at a set temperature like 1000°C, it ensures complete combustion or decomposition of volatiles. The working principle requires stable, uniform temperature to achieve consistent results across samples. Its purpose is critical for quality control in industries dealing with minerals, catalysts, and construction materials, providing a simple yet vital measure of a material's volatile content and, by inference, its purity or composition.
Trutherm manufactures 1000 Degree Celsius (°C) Loss on Ignition Furnace 450 x 450 x 900 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 450 x 450 x 900 MM chamber with usable chamber volume of 182.3 litre, approximate power load of 23.7 kW, square 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.
