SX3 Series Ceramic Fiber Muffle Furnace

Ceramic Fiber Muffle Furnace

Sintering, melting, elemental analysis and physical measurement within 1200°C of precise control.


  • Mirror stainless steel mouth, long-term use will not change color.
  • Imported double insulated ceramic liner, stable performance.
  • Vacuum forming polycrystalline mullite fiber furnace, high efficiency insulation.
  • In the double shell, the air sleeve is insulated, and the double guiding air passage.

SX4 model also has the following characteristics:

  • Adding exhaust devices is beneficial to ashing.
  • Split design, circuit detachable, easy to maintenance and repair.
  • P model is program temperature control type, program temperature controller can programme multistage program.
