For high-temperature testing procedures like loss-on-ignition or ashing, muffle furnaces are employed. These are compact countertop heating sources that use firebrick walls that are insulated to maintain high temperatures. The basic principles of thermal convection and thermal radiation are used to heat the air inside the chamber of a lab muffle furnace, sometimes referred to as a retort furnace. Our offerings operating at 1400 Deg C at high temperatures, silicon carbide rods, and MoSi2 (molybdenum disilicide) are used. The heating zone is the most important component of this product. These are widely popular for heating laboratory items in educational and research institutes.
