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 1100 Degree Celsius (°C) Loss on Ignition Furnace 800 x 420 x 420 MM Chamber for buyers who search by exact machine type, chamber size and 1100°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 800 x 420 x 420 MM chamber with usable chamber volume of 141.1 litre, approximate power load of 21.4 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.

Uniform chamber heating and a simple door-loading design make a muffle furnace straightforward to standardise across multiple operators and shifts.
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.
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.
