Laboratory stoves and muffles: What are the differences and applications?


It is an essential equipment in laboratories and is also known as drying oven; is used for drying and sterilizing glass and metal containers; now, the muffle is also an oven, but usually intended for cooking ceramic materials and for smelting metals through thermal energy., in KASLTEIN we have the different models of stoves and muffles to avoid confusion, you should follow the link HERE

The muffle can reach very high temperatures between 0 and 1700ºC, has the ability to heat quickly with a minimum of energy consumption, is not suitable for working at low temperatures and the stove or Drying Oven can reach up to 300°C of temperature and its internal chamber is made of stainless steel. Heat transfer is by air flow.

Differences between the stove and the laboratory muffle.

  • The muffle is used for substance calcination, substance drying, casting and control processes and the stove serves for material drying and for drying chemical salts at low temperatures.
  • The muffle monitors and regulates the temperature at all times so that it works more controlled than a stove.
  • The Drying Oven can reach up to 300°C of temperature, however, the muffle can reach temperatures from 500°C to 1800°C.
  • Inside the stove it is possible to dissipate the hot air thanks to the air flow achieving a uniform temperature and the muffle must always be used indoors, with an ambient temperature between 15°C and 40°C.
  • In the stove the heat transfer is by air flow; muffle and heat transfer is produced by radiation
  • The muffle walls are made of plates of thermal materials and insulating, and in the oven its interior is designed in stainless steel.
  • The main difference between the stoves and the muffles is in their temperature and the muffles only reach which is covered by refractory material, which allows a uniform heat delivery inside, reaching temperatures of up to 1.700°C. and the stoves can reach up to 300°C of temperature

Applications of the laboratory stove.

  • Dry chemical materials and salts, regularly at temperatures between 60ºC and 300ºC.
  • They are used at a temperature of 37°C to culture bacteria, fungi.
  • Dry and sterilize glass and metal containers in a laboratory.
  • Its use allows to remove all moisture from the containers.
  • By using it, any possibility of contaminating biological activity in the containers is eliminated.
  • Functionality is to heat, dry, harden or sterilize materials and parts of laboratory equipment.
  • They are basically used for drying materials, extracting high amounts of water from samples, sterilizing and drying dishes.
  •  In the heating and relaxation of parts sterilization of laboratory implements, heat testing for electronic products, etc.

Applications of laboratory muffle.

  • Used especially for the treatment of materials such as ceramics, metals and glass.
  • For thermal treatments or the destruction of organic and plastic elements.
  • They are used in thermal treatments, calcination tests, incineration of organic and inorganic samples and cooking of ceramic materials, among others.
  • It is used to carbonize organic substances in the ignition or ash analysis tests and analysis for quality control. 
  • It is used for substance calcination, substance drying, casting and control processes.
  • It is used for cooking ceramic materials and for smelting metals through thermal energy.
