The muffle is a laboratory furnace used to perform procedures that need a uniform exposure of high temperatures. They are used to calcinate substances and melt them, among other control processes. They are also used for heat treatment of cleaning and hardening injection molds.

The muffle consists of a closed chamber, made of refractory material. This consists of a door, through which you access the interior of the cooking chamber, where there is located a hole to observe and introduce probes for the verification and recording of the temperature inside the muffle. On the roof side, there is a hole where gases come out of the chamber and the walls are designed with insulating thermal plates.
