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 1200 Degree Celsius (1200°C) Annealing Furnace 885 x 700 x 700 MM Chamber for buyers who search by exact machine type, chamber size and 1200°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 885 x 700 x 700 MM chamber with usable chamber volume of 433.7 litre, approximate power load of 33.7 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.
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.
A muffle furnace is usually the first furnace a lab installs, since it covers the broadest share of everyday heating, drying and ashing tasks before more specialised equipment is added.
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.
