TGA stands for Thermogravimetric Analysis. This is a highly specialized furnace that is part of a TGA instrument, used to measure a sample's weight change as a function of temperature. Operating up to 1000°C or more, it provides ultra-precise temperature control and weight measurement. The working principle involves suspending a tiny sample in a controlled atmosphere (air, nitrogen, etc.) inside the furnace while continuously recording its weight on a sensitive microbalance. Its purpose is to study thermal stability, decomposition temperatures, oxidation, and composition of materials in research and quality control labs.
This configuration is suitable when the sample load must fit a 100 x 100 x 225 MM chamber with usable chamber volume of 2.4 litre, approximate power load of 4.1 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.

Trutherm manufactures 1400 Degree Celsius (°C) TGA Furnace 100 x 100 x 225 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.
A muffle furnace isolates the sample from direct contact with heating elements or combustion gases, giving cleaner, more repeatable results than an open flame or hot-plate process.
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.
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.
