A revolutionary system for microwave enhanced reactions

UltraCLAVE unit

As microwave chemistry is the best available technology for advanced materials processing, Milestone
introduces the UltraCLAVE, an advanced microwave Labstation with an entirely new concept by design and operating principle.
Early researchers investigating the use of microwave energy to accelerate chemical reactions used domestic microwave ovens for their experiments. Today, the same basic concept is used for most laboratory units - a multimode, microwave reflecting cavity with a door. The major limitation of conventional laboratory microwave systems is due to inherent compromises in the reaction vessel technology: reaction vessels placed in the microwave cavity must be constructed of materials that are microwave-transparent, chemically resistant, and inert.
The UltraCLAVE removes existing limits, allowing for larger sample masses, larger batch sizes, and higher temperatures and pressures. At its heart is a single, large reaction chamber. Individual reactions are exposed to a uniform microwave field and processed under identical temperature and pressure conditions.
A key innovation in the UltraCLAVE is pressurizing the reaction chamber prior to heating the contents. This unique approach prevents boiling, sample loss, and cross-over between the individual, open vessels.

The UltraCLAVE unique design and operating principle

The design and operating principle of the UltraCLAVE are entirely unique.

The UltraCLAVE advantages

  • The largest volume single microwave reactor
  • The highest temperature and pressure conditions attainable, well beyond what can be demonstrated in conventional microwave systems, for closed vessel processing
  • Largest single sample mass
  • Highest batch count of discrete samples. Multiple samples experience identical temperature and pressure conditions
  • Automatic operation once the samples are prepared: Load rack - Set parameters - Press START
  • Significantly reduced labor compared to conventional microwave systems
  • Significantly reduced consumables compared to ALL conventional microwave systems
