Ethos Easy

microwave sample preparation

How EASY can microwave sample preparation become?

ETHOS EASY is the most advanced yet easy to use microwave digestion platform we have ever manufactured. It offers a perfect integration between microwave hardware, user interface, digestion sensors and pressure vessels.

System description

The range of sample types requesting microwave digester and analysis for trace metals has grown significantly in recent years. At the same time, sample workloads have increased, and turnaround time reduced.
In addition, the development of collision cell ICP-MS has widened its applicability to more complex sample types placing additional demands on microwave acid digestion: its lower detection limits and fast analysis time require lower blank contribution and higher throughput in sample preparation techniques.
In response to these demands, Milestone has developed the new microwave digestion oven ETHOS EASY, specifically designed for closed vessel microwave acid digestion, with full control of all reaction parameters.

rugged, reliable microwave platform

Rugged, reliable microwave platform

While other manufacturers use molded plastic, Milestone uses 18/8 stainless steel construction throughout which creates the most durable, reliable, and safe microwave system available.


The microwave cavity has a volume of over 70 liters, the largest currently available. Therefore, digestion rotors with more sample places can be accommodated, incresing both productivity and sample throughput. Secondly, it improves the inherently safety because a larger cavity contains gases escaping from vessels in a more efficient way, in case of a sudden over pressurization.


The ETHOS UP is equipped with two 950 Watt magnetrons for a total of 1900 Watt. The system additionally employs a rotating diffuser that evenly distributes the microwaves throughout the cavity. High power coupled with this diffuser enable very fast heating of high throughput rotors and the complete digestion of the most difficult samples.


For additional safety, the ETHOS UP features a full stainless steel door with an innovative opening and self-resealing mechanism. Should there be a sudden over pressurization of the cavity, the door slightly opens for rapid and safe pressure release and the microwave power is instantaneously cut off. Immediately afterwards, the door is pulled back, resealing the microwave cavity.

Sensors for unparalleled digestion control

In a digestion process, the temperature controls the sample decomposition and directly affects digestion quality. Milestone pioneered the use of infrared sensors combined with an in-situ temperature sensor. Today, Milestone innovates again by combining all the benefits of in-situ and infrared sensors into the Milestone easyTEMP, a direct contactless temperature sensor.

Temperature control with easyTEMP

The easyTEMP contactless sensor directly controls the temperature of all samples and solutions, providing accurate temperature feedback to ensure complete digestion in all vessels with superior safety. This technology combines the fast and accurate reading of an in-situ temperature sensor with the flexibility of an infrared sensor.
The ETHOS UP software provides digestion history traceability and temperature measurement for every sample. Temperature diagrams and profiles are displayed in real-time, and can be saved on the ETHOS UP terminal.
In combination with our 'vent-and-reseal' vessel technology, these sensors ensure complete and safe digestions without any loss of volatile compounds.

  • ● Increased ease of use and productivity

  • ● Enhanced control in all vessels

  • ● Fast and accurate temperature measurements

  • ● Superior digestion quality

Smart software to save your time!

Hundreds of applications including all US EPA methods, are preloaded in the Ethos Easy terminal virtually eliminating any need for method development. To further simplify the workflow in the lab the Ethos Up is equipped with a backlit logo that indicate the actual status of the digestion process.
