The Milestone PYRO is an advanced microwave muffle furnace suitable for ashing, sulfated ashing, loss on ignition (LOI), residue on ignition (ROI), fusion and other high-temperature reactions under controlled conditions. The PYRO features interchangeable configurations for ultrafast heating setup, high sample throughput setup and sulfated ashing setup, making it the most flexible and adaptable microwave muffle furnace available in the market.
The PYRO microwave ashing systems’ unique design eliminates equipment corrosion and acid fume pollution, greatly reducing analyst exposure to acid fumes. The PYRO also dramatically reduces ashing times by ramping from room temperature to 800 °C in 8 minutes making ashing of samples a fast, effective and simple process.
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.
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.
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 Sulfate 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.
Reduced Operating Costs
The PYRO has an extremely fast heating rate. A typical ashing temperature of 800 °C can be reached in 8 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.
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.
