NOVELTY - The utility model claims a laboratory digestion backflow special electric furnace, comprising an electric furnace main body and a graphene cover plate; the graphene plate covers the surface of the electric furnace main body; the graphene plate is fixedly connected or detachably connected with the electric furnace. the graphene plate is connected with the electric furnace through the bolt. The utility model on the original structure of the electric furnace, increases the graphene plate, effectively prevents the electric furnace panel is corrosion and heating is not uniform, because of the unique physical property, it can make the heating uniform, temperature response is timely, and also reduces the energy consumption.
