Fold-Down Door Muffle Furnace

A muffle furnace is used for high-temperature applications like ashing, heat treatment, and material testing in labs and industries. It works by enclosing a sample in an insulated chamber, which allows for precise and uniform heating without direct contact with heating elements or combustion gases. Other common uses include annealing, sintering, and loss-on-ignition analysis.
