Milestone Pyro och Pyro SA

Microwave ashing

The PYRO systems unique design eliminates equipment corrosion and acid fume pollution, greatly reducing analyst exposure to acid fumes.
The PYRO dramatically reduces ashing times: it is able to ramp from room temperature to 800 degrees in less than 30 minutes.
The PYRO SA is identical to the PYRO, but it is equipped with an additional module specially engineered for sulfate ashing procedures.

PYRO benefits

Reduced operating costs

The PYRO has an extremely fast heating rate. A typical ashing temperature of 800°C can be reached in less than 30 minutes from room temperature.
This eliminates the necessity of running the system overnight, and avoids the lengthy heat up times associated with electrical resistance furnaces, dramatically lowering average power costs.

Milestone ashing crucibles

High sample throughput

The PYRO has an extremely large working cavity area.
You can easily accommodate up to twelve standard 40 mm wide crucibles at a time.

More comfortable working conditions

No heat neither odors added to the laboratory. The special microwave-transparent ceramic muffle furnace is an outstanding insulator, minimizing heat loss and transfer to the surrounding area.
The ambient temperature of a laboratory will be unaffected, even when the unit is running at its highest temperatures.
The built-in exhaust system of the PYRO removes fumes from the interior of the furnace and directs them through an exhaust hose to a fume hood or other outlet.

PYRO Sulphate Ashing benefits

Ashing of pharmaceutical, polymer, and food samples often involves the use of H2SO4. Hot sulfuric acid vapor released during these procedures is hazardous to analysts and corrosive to equipment.

The PYRO Sulphate Ashing enables analysts to add H2SO4 to samples and place crucibles directly into the microwave muffle furnace without a preliminary charring step.
The system is designed for complete operator safety and long life, and performs the complete sulfate ashing procedure in only 60-90 minutes.

Technical features

Porous ceramic honeycomb frits built into the side walls of the muffle furnace allow a constant stream of air to pass over the sample crucibles.
The combination of microwave superheating and the oxygen from the air flow results in a dramatic reduction of ashing times.
The high-efficiency microwave energy coupling characteristics of the silicon carbide heating inserts allows the use of any type of crucible (metal, porcelain, quartz, etc.) within the microwave furnace.

User interface

Automatic, real-time monitoring and feedback-based control of multiple parameters offers unsurpassed process control.
Simply recall a factory stored program or create a new one.
Press Start, and the system will automatically follow the defined temperature profile, utilizing a sophisticated PID algorithm.
