Electric Box-Type Muffle Furnace

The electric muffle furnace generates high temperatures through resistance heating elements, with the furnace chamber using insulation materials to reduce heat loss. It is used for laboratory heating processes such as sample ashing, melting, and heat treatment, and is applied in chemical, material, and environmental fields for compositional analysis or material modification.
Selection
Select the furnace chamber volume based on the sample size, match the maximum temperature according to process requirements (typically 800–1700℃), and ensure the temperature control accuracy meets experimental repeatability. Consider heating rate and temperature uniformity. Choose quartz fiber or ceramic lining depending on corrosiveness, and match power and power supply specifications to site conditions.
