The price of a muffle furnace varies depending on many factors, such as capacity, temperature range, control accuracy, heating elements, brand, etc. The price range ranges from a few hundred yuan to hundreds of thousands of yuan. The details are as follows: Small laboratory muffle furnace: The capacity is generally 5L-30L, the temperature range is 1000℃-1200℃, it is heated by resistance wire or silicon carbon rod, the structure is relatively simple, and the price is usually between 3,000 yuan and 20,000 yuan.  Medium-sized muffle furnace: with a capacity of 30L-100L and a temperature of 1400℃-1700℃. It usually uses more high-temperature resistant heating elements, such as silicon-molybdenum rods or molybdenum wires, and is equipped with a more precise temperature control system. The price ranges from 20,000 yuan to 80,000 yuan.  Large industrial grade or customized muffle furnace: with a capacity of more than 100L, or with a higher temperature limit, stronger insulation performance, or special design, such as continuous feeding, vacuum environment, etc., the price may exceed 100,000 yuan, or even reach hundreds of thousands of yuan.
