Phoenix Black

The world’s safest and fastest muffle furnace
Ash up to 15 samples at one time
Meets requirements of electrical and microwave muffle furnaces
Use any type of crucible normally used in conventional ashing systems, even platinum

Phoenix Black

The Phoenix BLACK is the new updated microwave ashing system from CEM. Microwave ashing has a lot of advantages.

Discover all the new features

Fast and Efficient

  • The Phoenix Black can perform ash analysis 10 times faster than a traditional muffle furnace, allowing you to respond more quickly to changes in the production process.
  • Ramp to temperature in minutes.
  • One-step ashing, complete pre-ash inside furnace without the need for a Bunsen burner.



  • Temperature verification and calibration for ISO and GLP practices are quickly and easily performed with a NIST traceable thermocouple.
  • IQ/OQ/PQ service available for turnkey validation and audit traceability.
  • Meets all requirements for methods that specify “electrically heated” furnaces or “microwave heated” furnaces.



  • Active ventilation keeps the lab free from soot and odors. No need to use a fume cabinet!
  • Patented quartz fiber crucibles cool to the touch in seconds.
  • Integrated sensors hold cavity door open when furnace door is removed or when overheating occurs.


Easy to use

  • Thanks to the touchscreen it’s easy to start or program methods with automatic start time and temperature ramps.
  • Available as a workstation pair with balance and printer or PC for automatic results – no more manual calculations needed.
  • The Phoenix BLACK can use any type of crucible that may be used in a conventional muffle furnace, including platinum.



  • The Phoenix BLACK is available with your choice of either a high temperature or a high capacity furnace.


High Temperature Furnace

  • Heats up to 1200 °C
  • Holds up to 8 (20/50 mL) or 5 (100 mL) Quartz Fiber Crucibles.

High Capacity Furnace

  • Heats up to 1000 °C
  • Holds up to 15 (20/50 mL) or 12 (100 mL) Quartz Fiber Crucibles.
