Fours à chambre universel

A laboratory chamber furnace is a heating device that meets the precise temperature control and temperature uniformity requirements of laboratory work. It is a standard piece of equipment in many labs, used for a wide range of applications such as ashing or heat treatment of materials. Laboratory chamber furnaces are typically known as muffle furnaces or box furnaces. They are also available in a cylindrical format known as tube furnaces.

Laboratory chamber furnaces are available with a range of maximum temperatures. The maximum temperature is dependent on the type of heating elements used in the construction. The most common have metallic wire heating elements with a maximum temperature in the range of 1000°C to 1200°C. Laboratory furnaces with silicon carbide heating elements can achieve 1600°C and with molybdenum disilicide heating elements can achieve 1800°C.

A laboratory chamber furnace is designed to heat samples contained within a chamber. The samples are loaded into the chamber for processing. The user inputs a setpoint into the furnace controller, and the temperature will increase accordingly. Heat is applied evenly within the chamber, which gradually heats the samples within.

Laboratory chamber furnaces can be used for a wide range of applications that include ashing, heat treatment of materials, annealing, calcination, carbon nanotubes production, crystal growth, curing, loss on ignition analysis, thermogravimetric analysis, quenching, and sintering.
