A laboratory box furnace is primarily used for high temperature sintering, metal annealing, quality inspection, and similar applications in universities, research institutes, and industrial enterprises. Its core principle involves generating heat by passing an electric current through heating elements, creating a uniform high temperature environment within an enclosed chamber lined with refractory materials, thereby meeting various heat treatment needs.
A muffle furnace, also known as a box furnace or vacuum furnace, is a heating device designed to operate under high temperature and high purity atmospheric conditions. It is commonly used in laboratory environments for sample pre treatment, elemental analysis, and experiments involving special materials. This type of furnace is characterized by precise temperature control, adjustable atmosphere, simple operation, and safe use, making it widely applicable in fields such as materials science, chemistry, and electronics. As a high temperature heating instrument, muffle furnaces can typically reach temperatures of 1000℃ or even 1300℃. Our compact lab muffle furnace, however, can achieve temperatures up to 1750℃, meeting the experimental needs of high melting point and high stability materials, and providing critical technical support for materials research and sample processing.
A lab high temperature sintering furnace is a versatile, multifunctional industrial heating device that combines the advantages of open chamber batch processing from box furnaces with the atmosphere controlled, sealed tube capabilities of tube furnaces. It integrates a sealed tube chamber inside the furnace or connects external tube components to the main box type chamber.
