Improve Results with Quartz Fiber Crucibles

CEM’s unique, patented quartz fiber crucibles dramatically reduce ashing times and cool in seconds. The quartz fiber material allows oxygen to circulate around the sample speeding combustion even with our unique crucible caps in place.

  • Reduce analysis time by as much as 97%!
  • Cools in seconds
  • No need for desiccation
  • Speeds sample oxidation using a flow through advanced material design
  • Withstands temperatures up to 1,000 °C
  • Unbreakable

Crucible caps can be used with our 50- or 100-ml crucibles. Try them out next time you have to ash a sample that needs to be contained.

Ideal for low ash samples and samples with high organic content
  • Contains the sample when ignition occurs
  • Reduces contamination
  • Improves accuracy on ROI and LOI determinations
 
Automatic replenishment programs, yearly contracts and volume pricing are available for quartz fiber crucibles. For more information and part numbers, please visit our Consumables page.

Self-Sealing Quartz Crucibles
For oxygen-free ashing, self-sealing quartz crucibles are available. These crucibles can be used for Carbon Black determination in polyethylene and polypropylene and eliminate the need for slow, fragile tube furnaces.

Ashing under Inert Gas *
The super-fast muffle furnace allows the rapid determination of soot and carbon fibers and carbon nanotubes in polymers

The Phoenix can be used as a rapid plastic incinerator with inert gas atmosphere. This enables the rapid ashing of a variety of different plastics and rubbers, for the determination of soot or carbon content and the content of carbon nanotubes. The result: What previously took hours, is now achieved in minutes. The application areas for such plastics compounds are typically in the aircraft and automobile (bumpers, moldings, fittings, sinks, counter tops, finished parts, etc.) amongst others.

Since the material properties of plastic compounds depend essentially on its filler content, a rapid determination of this filler (carbon black, carbon fiber, carbon nanotubes, etc.) is required for an effective process control. Substantial cost savings can be made by a quick intervention in the current production process. With a conventional muffle furnace, polymer and filler are incinerated together in a crucible and thus the filler cannot be measured. The alternative is to use the Phoenix with an inert gas atmosphere such as a nitrogen purge.

Results are obtained in just 10 minutes. The heating muffle is purged with an inert gas such as nitrogen. The plastic polymer is carbonized and exits the crucible but the carbon-containing filler in the crucible remains. The built-in fan removes smoke, heat and fumes automatically, thus increasing the active safety at work.

Material Science
The inert gas option can also be used in a variety of applications related to material science. Various publications have highlighted the benefits of using microwave energy and we can now offer a solution for reactions requiring an inert atmosphere.
Microwave irradiation quickly applies the energy necessary to achieve high temperatures, enabling reactions to be performed quickly and efficiently. The instant power on / power off provides for a steep rise in temperature during the heating but also for a steep decline during the cooling resulting in high quality materials.

Microwave energy has been used for making materials such as:

Quantum Dots
Zeolites
Metal Oxides
Metal Organic Frameworks
Gold, silver, and other metal nanomaterials
Nanocomposite materials
Nitride powders
Lithium ion materials


*CEM cannot fully guarantee an oxygen-free environment using this process.




Calibration Source Instrument (NIST traceable)
The calibration source instrument and built-in system software allow rapid calibration of the temperature control circuitry of the Phoenix Microwave Ashing Systems. A NIST traceable certificate of calibration is supplied with the instrument.

Dual Element ThermocoupleDual Element Thermocouple (NIST traceable)
The type K Dual Element Thermocouple contains two thermocouples in one sheath. While one thermocouple controls the operating temperature, the second thermocouple can be connected to a digital thermometer to verify the accuracy of the controlling thermocouple. It is NIST traceable with a certificate of calibration.







Cooling FanCooling Fan
The furnace cooling fan rapidly reduces heat to the starting temperature.





All Phoenix Microwave Ashing Systems are available with workstation options including a balance and printer.
