Muffle Furnace LMF-J70 has a maximum temperature of 1700℃ and is designed to operate continuously at a working temperature of 1600℃. It features a compact 1-liter chamber, making it suitable for small-scale high-temperature applications. The furnace uses durable silicon molybdenum rods as heating elements, ensuring efficient and consistent heat delivery. Our muffle furnace chamber features a three-layer full fiber lining for superior insulation. Its outer shell is made of treated carbon steel, finished with acid pickling, phosphating, rust removal, and electrostatic spraying for durability and a clean appearance.
