This furnace heats materials, typically metals or glass, and allows them to cool slowly to remove stresses and improve ductility. It operates at controlled temperatures (e.g., 550°C for metals) to initiate recrystallization or stress relief without altering the material's shape. The working principle involves a chamber that provides uniform, controlled heat, often with programmable cycles for temperature ramping and soaking. Its purpose is to enhance workability, prevent cracking during service, and prepare materials for further processing. Widely used in glass manufacturing and metallurgy, it ensures product reliability by eliminating internal weaknesses.

Trutherm manufactures 1400 Degree Celsius (1400°C) Annealing Furnace 230 x 170 x 240 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.
This configuration is suitable when the sample load must fit a 230 x 170 x 240 MM chamber with usable chamber volume of 9.4 litre, approximate power load of 7.1 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.
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.
