Laboratory Muffle Furnace is a specialized heating device used in labs for high- temperature applications, such as ashing, annealing, and heat treatment of samples. It has a heat resistant chamber generally made using refractory materials like brick or ceramic, to ensure tolerance to extreme temperatures. The Laboratory Muffle Furnace is equipped with temperature controls, heating elements, and a programmable controller for precisely regulating and maintaining the desired temperature. It often has a door or lid that can be opened or closed to secure the samples inside. It finds application in material testing, scientific research, and industrial processes requiring controlled high- temperature environments.
