Phoenix Microwave Muffle furnace
Reduce analysis times from hours to minutes!
Many diverse industries from food to petroleum products use muffle furnaces to ash product for analysis.
Phoenix microwave muffle furnaces provide results in minutes instead of hours! Ashing can now be used for process control, ensuring a higher quality product.
Any crucible used in a conventional muffle furnace can be used in the Phoenix, even metal!
Phoenix muffle furnaces perform high temperature applications up to 97% faster than conventional designs.
Phoenix microwave-powered muffle furnaces are available in configurations to fit any ashing need. They are fast, accurate and easy-to-use

Reduce analysis time by as much as 98% with CEM Quartz Fiber Crucibles!
CEM’s unique quartz fiber silica crucibles dramatically reduce ashing times and cool in seconds. The quartz fiber material allows oxygen to circulate around the sample speeding combustion. For oxygen-free ashing, self-sealing quartz crucibles
are available. Ideal for carbon black determination in polyethylene and polypropylene.
- Speed sample oxidation using a flow-through advanced material design
- Withstand temperatures up to 1000 °C
- Disposable
- Safe (Cool in seconds, no need for dessication, eliminate the risk of burns from handling crucibles
- Unbreakable
- Available in 20, 50, or 100-mL sizes
Self-Sealing Quartz Crucibles
For oxygen-free ashing, self-sealing quartz crucibles are available. Ideal for carbon black determination in polyethylene and polypropylene.
