The Game Changer in Microwave Digestion


The Game Changer in Microwave Digestion

The ultraWAVE fully endorses our vision in microwave sample preparation: it has already revolutionized and enhanced the way analytical chemists think to sample preparation for trace metal analysis in hundreds of laboratories all over the world.


    • High performance. The highest temperatures & pressure capabilities and the fastest cooling time.
    • Increased throughput. Double throughput of traditional microwave acid digestion instruments.
    • No batching required. Simultaneous digestion of any sample type combination.
    • Ease of use. Cleaning of digestion vials is not necessary. No vessel assembly/disassembly.
    • Expertise and Support. 30-years experience at your lab with the Milestone Connect.
    • Compliance. USP 232/233 Chapters, ICH Q3D Guidelines and FDA regulation 21 CFR part 11.


Four, five, eight, fifteen, twenty-five, twenty-six, and twenty-six position ultraWAVE rack configurations, as well as combinations thereof, are available. TFM, quartz, and disposable glass vials are provided, with loose TFM lids to ensure pressure equalisation. Unlike traditional microwave digestion systems, there is no need to assemble or disassemble the vessel. The use of disposable glass vials eliminates the need for cleaning, improving the lab’s workflow even further. The automated closure and opening of the vials, as well as the quick assembling of the vials, reduced handling time by up to 50%.


The ultraWAVE, like other Milestone products, has been designed with operator safety in mind: it may be used with any acid or mix of acids, and each reactor is pressure tested to 330 bar. The working area is surrounded by a thick acrylic shield, and runs cannot begin until the chamber clamps are in the correct position. Temperature and pressure are monitored 20 times per second, with the microwave power automatically adjusted to manage even highly exothermic reactions.


There is no need to batch samples into identical types; any combination of sample types (food, environmental, polymer, cosmetic, pharmaceutical, geological, chemical, and petrochemical) can be digested simultaneously. There is no need to build a method because the same procedure may be used to practically any sample. For the first time, any matrix’s blanks and reference standards can be digested alongside samples, allowing for real quality control during the digestion process.


The ultraWAVE, which can operate at up to 199 bar pressure and 300°C temperature, can completely digest even the most difficult materials and vast amounts of organics, exceeding any other microwave digesting system. Unlike traditional microwave digestion systems, every sample is directly controlled in terms of temperature and pressure, eliminating the requirement for a reference vessel or indirect controls like infrared temperature sensors.
The ultraWAVE heats up faster, cools down faster (10 minutes from 200°C to room temperature), and can handle more pressure and temperature than any other system. There is no cross contamination among samples in the ultraWAVE. Because less acid is needed and vials have a much smaller surface area, blanks are significantly lower than with traditional microwaves.

Efficient and Cost-Effective


The ultraWAVE is substantially easier to use than any other standard microwave digesting device, dramatically boosting laboratory work flow. From start to end, up to 26 samples can be processed in 45 minutes. It goes without saying that the ultraWAVE sample throughput outperforms all other microwave technologies.
All samples are processed at the same temperature and pressure in a single run, removing the need for repeated digestion cycles for various samples or matrices. The use of disposable glass vials minimises the need for cleaning, boosting ultraWAVE productivity even further.


The ultraWAVE no longer requires the opening and closing of vessels, as well as the installation and disassembly of rotors. The system’s handling is drastically reduced, and time-consuming and tiresome operations are removed.
The technology utilised in all ordinary microwaves causes harsh circumstances in TFM vessels, lowering their lifespan significantly. The ultraWAVE’s SRC technology is designed to help reduce operating expenses by using inexpensive and convenient vials that may be used to determine any metals or trace metals.
