The game changer
in microwave sample preparation.
The new UltraWAVE exceeds norms and breaks conventions!

Milestone´s unique Single Reaction Chamber (SRC) technology overcomes the limitations of all conventional microwave sample preparation systems:

  • High performance
  • Higher sample throughput
  • Improved workflow
  • Lower labor
  • Lower consumables costs

At the hearth of the UltraWAVE is a Teflon-lined 1 liter stainless steel reaction chamber, which serves both as a microwave cavity and a reaction vessel.
Samples are weighed into vials, and suitable reagents are added. Vials are placed in a rack, which is automatically lowered into the reaction chamber. The chamber is sealed and pre-pressurized with inert gas, which physically acts as a cap for the vials, avoiding boiling of the solutions and preventing cross contamination.
At the completion of the microwave run, a built-in cooling device rapidly lowers the temperature.


Ultrawave SRC technology

Improved workflow

The UltraWAVE operates up to 199 bar pressure and 300°C. Unlike all conventional microwave digestion systems, every sample is under direct temperature and pressure and temperature control- no needs to rely on a reference vessel or to an indirect control such as infrared temperature sensors.
This assures complete control of the digestion process in every sample.


A thick acrylic shield surrounds the work area, which lowers into position automatically as the chamber is closed.
The PID controller monitors pressure, digestion and chamber temperature 20 times/sec, adjusting microwave power to control even highly exothermic reactions.

UW safety

Fast cooling

At the completion of the microwave run, the UltraWAVE built-in cooling device enables the temperature to lower from 270°C to 80°C in just 12 minutes.

UW cooling

Low operating costs

No vessel assembly/disassembly is required, vessel cleaning is eliminated with disposable glass vials, and method development is virtually eliminated.
There are also major savings on consumables costs, which is important for high throughput labs using closed vessel digestion.

Analytical performance

  • One digestion method
  • Larger sample amount
  • High sample throughput
  • No cross contamination
  • Standard method compliance

      ... for all samples

      With the Milestone UltraWAVE, any combination of sample types can be digested simultaneously; no need to batch samples into identical types.

      No method development is needed, as the same method can be used for almost every sample type.
      For the first time, blanks and reference standards of any matrix can be digested alongside samples, enabling true in-run digestion quality control.
