Milestone Pyro XL

Why the PYRO XL?

The determination of ash content is an important test performed daily in thousands of laboratories.
While ashing is a relatively simple process, conventional muffle furnaces are inefficient in a number of respects, which often leads to the process being tedious and time consuming.
On the other hand, electrical resistance furnaces are typically costly to maintain due to high energy consumption.
Additionally, both of these types of instruments have a tendency to diffuse heat making the surrounding laboratory environment uncomfortable due to heat and odors.
The application of microwave technology to dry ashing procedures has presented a breakthrough in the process and quality control of samples like polymers, petroleum, food and feeds, pulp paper and pharmaceuticals.
However, the ashing of high volumes of these types of matrices, which generally tend to generate a high quantity of fumes, have been challenging.

Milestone Pyro XL why

Technical features

A special microwave-transparent ceramic muffle allows microwave radiations to pass through and rapidly raise the temperature of a high-absorber material plate, located in the upper part of the cavity.
Sample crucibles are placed on a large clean quartz plate and an airflow is generated by a built-in exhaust system.
Temperature is controlled via a high-precision sensor located in close proximity to the bottom of the ashing crucibles.
The PYRO XL is operated using a stand-alone, color, touchscreen controller.
Running Milestone´s EasyCONTROL software, it provides the operator with a simple yet effective interface and has real-time monitoring and feedback of all microwave processes.

Benefits

Rapid heating

The PYRO XLs ability to ramp from room temperature to 800 degrees in approximately 30 minutes eliminates the need to keep the system on continually.

Large muffle cavity for high throughput

The PYRO XL has a large muffle cavity which can accommodate several crucibles simultaneously.

Crucibles

The high-efficiency coupling features of the silicon carbide plate allows for the use of virtually any type of crucible including platinum, nickel, porcelain, quartz and quartz fiber.

Comfortable working conditions

The ceramic muffle is an excellent insulator which minimizes diffusion of heat to the surrounding laboratory areas. The built-in exhaust system removes fumes from the interior and direct an exhaust hose to a fume hood or other outlet.
