Milestone S.r.l. - UltraWAVE - Microwave digestion system

Milestone’s unique Single Reaction Chamber (SRC) technology, first developed with the UltraCLAVE, overcomes the limitations of traditional microwave sample preparation.
At the heart of the system is a large sample chamber that is pre-pressurized with inert gas and heated with microwave energy.
The chamber serves both as a microwave cavity and a reaction vessel. Employing the same SRC technology as the UltraCLAVE, the UltraWAVE offers the same great benefits, but in a smaller benchtop instrument, making it accessible to every lab.
With higher performance, higher sample throughput, improved workflow, plus lower labor and consumables costs when compared with conventional closed vessel systems, the UltraWAVE is transforming microwave digestion.
And not only microwave digestion: its higher sample weight capability, greater digestion power, outstanding throughput and ease of operation means UltraWAVE can replace open vessel digestion, high pressure ashing and even block digestion in many applications.

Key benefits:

• Greater Ease of Use
  Compared to closed vessel digestion, the UltraWAVE is significantly easier to use and workflow is dramatically improved. No assembly/disassembly of vessels is required, and no vessel cleaning (with disposable glass vials).
  Direct temperature and pressure control of every sample ensures complete control of the digestion process.
  Any combination of sample types can be digested simultaneously; no need to batch samples into identical types.
  No method development is needed (the same method can be used for almost every sample type) and no need to use different rotors for different sample types.
  And for the first time, reference standards (any matrix) can be digested alongside samples, enabling true in-run digestion QC.
• Increased Productivity
  Compared to closed vessel digestion, labor costs are significantly lower because no vessel assembly/disassembly is required, vessel cleaning is eliminated with glass vials, and method development is virtually eliminated.
  There are also major savings on consumables costs, which can be significant for high throughput labs using closed vessel digestion.
• Lower Operating Costs
  The UltraWAVE has higher sample throughput than closed vessel digestion, even where closed vessel systems are used with high capacity rotors, due to quicker sample loading/unloading and shorter cool down time.
  And since there is no need to batch samples into identical types for digestion, workflow is significantly improved.
• Higher Performance
  Capable of operating up to 199 bar pressure and 300°C, the UltraWAVE enables complete digestions for virtually every sample type, outperforming any other microwave digestion system.
  The high pressure capability, and powerful microwave source enables higher sample weights to be digested.
  For example up to 2g of infant formula can be digested, 2-3 times higher than is possible with a high pressure rotor with closed vessel digestion, and very useful to labs at the limit of ICP-OES detection. Blanks are significantly lower than with closed vessel digestion, since less solution transfer occurs, quartz vials can be used and digestion acid volumes are lower.
