CEM offers accessories for the calibration and verification
of the temperature control circuitry to meet governmental
regulations for various applications.
 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 100 ml or 50 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
 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.

Automatic replenishment programs, yearly contracts and volume
pricing are available for quartz fiber crucibles.
 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 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.
 Digital
Thermometer
Verify the programmed temperature by connecting the digital
thermometer to the reference thermocouple.
 Cooling
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.
 Sulfated
Ashing Option
Ash pharmaceutical raw materials, excipients and finished
products in minutes, while safely removing and neutralizing
sulfur dioxide and nitric acid emissions to meet ISO 14000
regulations. The Phoenix
Sulfated Microwave Ashing Option features a vapor scrubber
system to safely remove harmful fumes from the furnace cavity
and neutralize any residual acid exhausted from the sulfated
ashing process.
- Meets requirements for USP 281 (ROI) & USP 733 (LOI)
- Built-in serial and parallel ports provide full
documentation of method, completion date, and time
- Menu-driven software permits simple entry and storage of
operating parameters for up to 20 methods
- Rapid disconnect feature allows system to be used as
either a standard ashing system or a sulfated ashing
system in less than 5 minutes without the use of tools
- Quartz furnace ceiling assures sample purity
- Easy-to-use
