A muffle furnace is a versatile high-temperature device widely used in laboratories, industrial settings, and research facilities. Its temperature range typically spans from 800°C to 1800°C, though some advanced models can exceed 2000°C. This wide range makes it suitable for applications such as material heat treatment, elemental analysis, ashing, and high-temperature experimental research. The specific temperature capability depends on the furnace's design and heating elements. Proper operation and safety precautions are essential to ensure optimal performance and longevity of the equipment.
