The application of microwave technology for ashing procedures has resulted in a significant improvement in internal quality control and in some cases sample preparation procedures.
While many laboratories still use a traditional muffle furnace or electrical furnaces to ash samples for process control purposes, these techniques can be time-consuming – often taking hours per run. This can result in high energy usage and ultimately, high operating costs. In addition, use of traditional furnaces have a tendency to diffuse heat and odors, which can lead to an uncomfortable working environment. To avoid subsequent high-energy usage, high-operating costs and increase total cost-effectiveness of a lab, we present microwave ashing and suphate ashing system PYRO featuring advanced muffle furnace. Milestone’s PYRO Microwave Muffle Furnace Ashing System offers an excellent alternative to conventional muffle furnace techniques. Our solution helped laboratories to optimize processes like residue on ignition and loss on ignition (LOI) in a variety of industries to improve their efficiency.

Advanced Microwave Muffle Furnace

Advanced Microwave Muffle Furnace

PYRO Sulphate Ashing

No preliminary charring step

Sulfuric acid can be added to the samples and crucibles can be directly placed into the microwave muffle furnace.

Short Ashing Times

Complete sulfate ashing procedure in just 1 hour.

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.

Reduced Operating Costs

The short ashing time 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.
