Productivity matters The ETHOS UP fully embodies Milestone’s philosophy in microwave sample preparation. Specifically designed for closed vessel acid digestion, it offers a perfect integration between microwave hardware, user interface, reaction sensors and pressure vessels.

Largest microwave cavity

Largest microwave cavity

watch The new Milestone ETHOS UP microwave cavity has a volume in excess of 70 litres, by far the largest currently available. What are the main implications if this design? Firstly, digestion rotors with more sample places can be accommodated thus improving productivity and throughput. Secondly, the unit is inherently much safer since a larger cavity better contains gases escaping from vessels, should there be a sudden overpressurisation.

Power matters too

Highest power

femme cherche rapport The ETHOS UP is equipped with two 950 Watt magnetrons for a total of 1900 Watt making it the most powerful microwave digestion system available for sample preparation.
The system additionally employs a rotating diffuser that evenly distributes the microwaves throughout the cavity. Very fast heating of high throughput rotors and complete digestion of the most difficult samples is assured.

Reaction sensors

Highest safety: Reaction sensors

site de rencontre gratuit 27 sans inscription The new ETHOS UP is equipped with the most advanced reaction sensors for complete quality control of the digestion conditions.
Direct temperature and pressure control are used in a reference vessel. In all vessels, contact-less temperature is used where the actual temperature of each and every vessel is continuously shown on the terminal during the microwave run, allowing an instant visual check of the digestion conditions. In addition, a contact-less pressure sensor monitors all vessels simultaneously, preventing any leakage or venting. The sensors ensure complete and safe digestions without any loss of volatile compounds.

Pressure-responsive door

Highest safety: Pressure-responsive door

classement des sites de rencontres en france The ETHOS UP features a full stainless steel door with an innovative opening and self-resealing mechanism. Should there be a sudden overpressurisation of the cavity, the door slightly opens for rapid and safe pressure release and the microwave power is instantaneously cut off. Immediately afterward, the door is pulled back, resealing the cavity.
For additional safety, an automatic door locking system does not allow the user to open the ETHOS UP door during the microwave run. At the end of the run, the door remains locked until the solutions have cooled down to a user preset temperature.

Milestone Connect

Milestone ConnectIncluded with the new ETHOS UP system is a unique web based application – Milestone Connect.
The app provides up to date information and extended instrument control from outside the laboratory with remote monitoring of every sample in the digestion run that ultimately helps to provide high quality sample preparation.
The app works on various external devices such as PC, tablets or smartphones connected to the ETHOS UP.
The integral database includes specific and detailed information on the installed equipment (list of parts, technical notes, user manual, video tutorials, etc), continuously updated application notes, a library of available scientific articles published in scientific magazines, and a help-on-line section that provides instant support available 24 hours a day, 7 days a week for our users.


User interface

Milestone terminalThe ETHOS UP is controlled via a compact terminal with an easy-to-read, bright, full-colour, touchscreen display. The terminal is provided with multiple USB and Ethernet ports for interfacing the instrument to external devices and to the local laboratory network. The terminal runs a completely new user-friendly, icon-driven, multi-language software to provide easy control of the microwave run. Simply recall a previously stored method or create a new one, press ‘START’ and the system will automatically follow the user defined temperature utilising a sophisticated PID algorithm. Hundreds of applications, including all US EPA methods, are preloaded in the ETHOS UP terminal. There is no need to input the number of samples or weights being digested, as the software will automatically regulate the microwave power accordingly. This assures a consistent quality of digestion and simplifies the use of the instrument.

Moreover, the ETHOS UP is equipped with a high definition digital camera, named SafeVIEW, that is interfaced with the instrument terminal. It allows the chemist to monitor the progress of the digestion whilst fully protected by the all-stainless steel door of the instrument. A video of the entire run is shown in real time along with the digestion figures.
