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.

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.

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.

The ultraWAVE is based on the SRC (Single Reaction Chamber technology), invented by Milestone several years ago (Patents pending). SRC technology achieves extraordinary performance capabilities combining microwave heating with a high-pressure reactor which acts simultaneously as microwave cavity and vessel. The ultraWAVE chamber is sealed, pressurized, heated, cooled, vented, and opened via a dedicated touch-screen control terminal. Loading a rack of samples into the chamber is the only manual operation in an otherwise fully automated process of microwave-assisted sample preparation. The outer surfaces of the vessel remain at room temperature throughout the entire microwave heating cycle. As a result, the ultraWAVE is dramatically less labor intensive and easier to use compared to conventional microwave digestion systems.

For optimized workflow

1. Loading

2. Closing and pressurizing

2. Heating and cooling

4. Pressure release and opening

 The ultraWAVE rack configurations include 4, 5, 8, 15, 19, 22 and 26 position and combinations thereof. Vials are available in TFM, quartz or disposable glass, and are fitted with loose TFM caps to ensure pressure equalization. Unlike conventional microwave digestion systems, no vessel assembly or disassembly is required. The use of disposable glass vials eliminates the cleaning step, further enhancing the lab’s workflow. The fast assembly of the vials, the automatic closing and opening cut the handling time, reducing the labour cost up to 50%.

Like all Milestone products, the ultraWAVE has been designed with operator safety of paramount importance: it has been developed for being used with any acid or combination thereof, and every single reactor is tested at a pressure up to 330 bar. A thick acrylic shield surrounds the working area, and runs cannot be started unless the chamber clamps are in correct position. Temperature and pressure are monitored 20 times/sec, automatically adjusting microwave power to control even highly exothermic reactions.

The benefits of SRC technology

Any combination of sample types (food, environmental, polymer, cosmetic, pharmaceutical, geological, chemical, and petrochemical) 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 nearly any sample. And for the first time, blanks and reference standards of any matrix can be digested alongside samples, enabling true in-run digestion quality control.

Operating up to 199 bar pressure and 300°C temperature, the ultraWAVE enables the complete digestion of extremely difficult samples and of large amounts of organics, outperforming any other microwave digestion system. Unlike conventional microwave digestion systems, every sample is under direct temperature and pressure control, so there is no need to rely on a reference vessel or to an indirect control such as infrared temperature sensors.
The ultraWAVE reaches high temperatures faster, cools faster (10 minutes from 200°C to room temperature), and is capable of higher pressure and temperature than any other system. The ultraWAVE does not suffer of any cross contamination among samples. Blanks are significantly lower than with conventional microwaves, since less acid is used and vials have a much less surface in contact with the analytical solution.

High Productivity

Typical sample turnaround time (number of samples in 8 hours).

The ultraWAVE accommodates inexpensive disposable vials.

Opening and closing the vessels, assembly and disassembly of the rotors are not required in the ultraWAVE anymore. The handling of the system is dramatically reduced, and tedious and time-consuming procedures are eliminated.
The technology used in all conventional microwave lead to create stressful conditions in the TFM vessels, substantially reducing their lifetime. The design of SRC technology in the ultraWAVE strongly contributes to the reduction of the running costs by using inexpensive and handy vials suitable for any metals and trace metals determination.

The ultraWAVE is controlled via a compact external terminal with an easy-to-read, bright, full-color, touchscreen display. Multiple USB and Ethernet ports are provided, for interfacing the instrument to external devices and to the local laboratory network. The terminal runs the Milestone easyWAVE, a completely new user-friendly, icon-driven, and multi-language software. Just recall a previously stored method or create a new one; press the Start icon and the system will automatically follow the user defined temperature profile using a sophisticated PID algorithm.
Hundreds of applications, including all US EPA methods, are preloaded, eliminating any need for method development.

The patented Milestone ultraCLAVE achieves extraordinary performance capabilities by combining SRC patented technology with the highest throughput available in the market.

The ultraCLAVE's utilization of SRC technology allows for the processing of mixed matrices in the same run with different chemistries and to use vials/racks instead of vessels/rotors, which essentially removes the handling step in sample preparation. The ultraCLAVE completely changes the rules in microwave sample preparation and sets new standards in digestion, enhancing the overall efficiency in elemental analysis. The ultraCLAVE is capable of running as many as 77 samples simultaneously at high temperature up to 300 °C and pressure up to 200 bar, thus enhancing lab efficiency.

The patented Milestone ultraCLAVE achieves extraordinary performance capabilities by combining direct microwave heating in a high pressure reactor, which acts simultaneously as microwave cavity and vessel. Microwave energy is introduced into the reactor through a unique microwave port. This focused-multimode cavity design ensures maximum sample heating efficiency. Heat generated in the reactor is removed by a re-circulating cooling system, and the stainless steel vessel remains at approximately room temperature throughout the entire heating cycle.
The ultraCLAVE is designed for simplicity of use. Loading a rack of samples into the chamber is the only manual operation required. The reaction chamber is sealed, pressurized, heated, cooled, vented, and opened all under computer control.
The system dramatically reduces the labor compared to conventional microwave systems.

Sample preparation is the most labor-intensive step in elemental analysis, as it requires assembling, closing, opening and disassembling of the vessels. These operations involve a lot of handling, which is directly affected by the number of vessels used. The ultraCLAVE with SRC technology, uses vials and racks instead of rotors and vessels, completely removing laborious handling. SRC technology is based on a stainless-steel reactor with a volume in excess of 4 L, which act as both a microwave cavity and digestion vessel. A 3.5 L PTFE vessel with a base load is introduced into the stainless-steel reactor. The operator places the samples and acids into vials with loose-fitting caps, places the rack in the ultraCLAVE and the digestion process begins (Step 1). By pressing “START” on the dedicated large screen terminal, the system automatically closes the stainless-steel vessel and clamps, loads the nitrogen pressure and runs the pre-selected microwave program (Step 2). After completion the vials are cooled using a powerful external chiller, pressure is safely released, and the main reactor opens, delivering the digested solutions ready for dilution and analysis (Step 3).

2. MW heating

3. Opening

The combination of stainless-steel reactor with microwave technology results in a digestion system with superb performance and abilities. The temperature range up to 300 °C allows for the digestion of virtually any sample, while the maximum pressure of up to 200 bar allows for digesting very large sample amounts. Highly reactive samples such as large amounts of food, pharmaceuticals, polymers and petrochemicals can be completely digested. Furthermore, the platform's flexibility found a natural fit in other analytical testing labs such as environmental, clinical and biological. The ultraCLAVE allows for the simultaneous digestion of completely different matrices with different chemistries, as the set conditions in the stainless-steel cavity are applied to all vials, ensuring complete digestion of all samples in the reaction chamber.

SRC technology offers high throughput without compromising productivity. The ultraCLAVE greatly reduces handling and operator time, eliminates the need to batch the samples and to clean of vials, resulting in a more productive approach to digestion across multiple industries. Most samples will be digested using a single program, eliminating method development and simplifying the digestion procedure. The ultraCLAVE is an efficient tool for mixed or similar samples. Lab throughput is greatly enhanced, with a digestion cycle taking about 60 minutes for 40 or 77 samples. Lab efficiency is improved by removing the need to batch samples, speeding up the digestion cycle and using inexpensive consumables. The ultraCLAVE offers superior productivity, ease of use and performance far surpassing any conventional digestion system.

Racks and vials with loose-fitting caps greatly simplify daily operation and reduces running costs. The ultraCLAVE racks are available in several configurations, from 6 to 77 individual samples, to accommodate varying sample throughput needs as well as large sample masses. The selection of vials includes high-purity PTFE, quartz and disposable glass. The use of disposable glass vials eliminates the tedious and time-consuming cleaning step, improving lab workflow. Rack handling is as simple as hanging it in the system. Moreover, SRC technology allows for the use of a single method regardless of the sample type and amount, making it possible to digest different matrices together in the same run.

Patented "Vent-and-Reseal" Technology

All Milestone rotors feature an enhanced 'vent-and-reseal' technology for controlling the inner pressure of all vessels with complete safety. This patented (US Patent 5,270,010) technology provides the operator with unsurpassed safety and performance capabilities: highest temperature and pressure, highest safety standards, ease of use, and very fast cooling (180°C to 40°C in 10 minutes). While other systems use membranes or burst disks that render a vessel useless after venting, the Milestone system releases only the excess pressure from the vessel. This ensures that there is no stress to the door of the microwave system and no loss of sample as could happen in the

 case of a membrane or disk bursting. The illustration shows 'vent-and-reseal' in action: the vessel cap is held in place by a dome-shaped spring (1). In the case of over pressure due to a highly exothermic reaction, the spring is flattened, allowing the cap to lift up slightly (2) releasing excess pressure. Immediately the excess pressure is released, the spring reseals the vessel (3), and the digestion continues. There is no loss of sample and no clean up needed. The microwave program continues to completion and no re-run is required. While there are other methods of venting, only Milestone has 'vent-and-reseal' technology.

Self-regulated venting

There is another approach to venting, but it implies limitations compared to Milestone's Vent-and-Reseal and Self-regulating technology.
