The muffle is a equipment used for the smelting of metals and for the cooking of materials, by using thermal energy. They are made up of different elements, which are necessary for its proper functioning, these are: an internal cabinet, a rear door, an external cabinet, temperature controllers and a control panel. It should be noted that only refractory materials must be used inside the muffle, since these are the only ones that withstand the temperatures that develop in it.

The muffle in the laboratories, is of fundamental use to heat ceramic materials to high temperatures, or to dry and calcinate precipitates and different products. It is for this reason that it is used, since it is a kind of oven that reaches temperatures higher than 200 °C. In addition, the muffle is also designed to fulfill other functions within the laboratory area, such as control processes, precipitate drying, precipitate calcination and smelting.

Implementation of muffles in the laboratory

The muffle is a laboratory instrument that can be defined as a type of oven, however, the way it works is more controlled, since, unlike the conventional oven, the muffle monitors and regulates the temperature at all times. The muffle reaches very high temperatures in order to fulfill several processes that need this type of characteristics in laboratories. Its main use in laboratories is for control processes, precipitate drying and heat treatment.

Having a muffle in the laboratory poses certain risks, such as the risk of burns, the risk of fire, explosion and poisoning, the release of flammable or toxic vapors, the risk of rupture of vessels and the risk of electrocution from indirect contact. That is why certain guidelines must be followed within the laboratory so that this does not occur, these would be:

  • Avoid touching the surface of the muffle as it may be hot if used previously.
  • Do not put samples with flammable chemicals in the ovens, as this can cause an explosive atmosphere.
  • Use containers suitable for the temperature reached.
  • Use face and eye protection in case of splashing.
  • Use a grounded socket base to avoid the use of multiple plugs that lead to overcharging.

Types of mufflers

The muffle has a type of insulating refractory material chamber, so if you want to use it, you need to introduce objects with these characteristics, because these are the only ones that can tolerate the high temperatures that are carried out in it. On the other hand, there is a great diversity of muffles for all types of laboratory, depending on the needs, however, it should be noted that all muffles have the same elements. Despite this, there are the following mules on the market:

  • Fuel muffle: It is characterized by reaching high temperatures and having a heat source separate from the cooking chamber that does not contaminate the sample with the flue gases.
  • The electric muffle: is a device used in laboratories to generate chemical and physical reactions, as a result of the increase in temperature.

Muffles

The muffle is a laboratory instrument used to perform procedures that require uniform exposure to high temperatures. In order to operate this equipment, it is necessary that the user has the necessary clothing, such as the gloves and the apron, to subsequently verify that the muffle is properly connected to the power source and process the desired samples.

The muffle is a team made up of different elements, which are necessary for it to function properly, these elements are: the internal cabinet, the rear door, the external cabinet, the temperature controllers and a control panel. However, although each muffle contains these elements as a base, there are several types of these: fuel muffles, electric muffles and those based on other principles.
