Muffle Furnace Manufacturers in Ahmedabad Brand: Hema The ability to isolate the material from the combustion gases is a key feature of a muffle furnace. This separation ensures that no contaminants are introduced during the heating process. The muffle furnace is typically used when the material must be heated in a clean, controlled environment to prevent oxidation or contamination. The atmosphere inside the furnace can be adjusted by controlling factors like the presence of oxygen or the introduction of gases like nitrogen. This ability to control the atmosphere is particularly useful in sensitive applications such as heat-treating metals or synthesizing chemicals.
