ETHOS One productivity

Fast Heating and Cooling of the Vessels

The ETHOS One is equipped with two magnetrons, with an installed microwave power of 1600 Watts. This enables very fast heating of high-throughput rotors.
Fast cooling of vessels is as important as fast heating. A heavy-duty airflow system, placed above the ETHOS One microwave cavity, rapidly cools the pressure vessels at the completion of the program.
An acid resistant flexible hose connects the exhaust fan to a fume hood, ensuring a safe working environment.

One Method Fits All

With the ETHOS One there is no need to adapt the digestion method to the number of samples being digested. The software automatically regulates the microwave power accordingly, while the reaction temperature remains the same regardless of the number of samples. This assures a consistent quality of digestion and simplifies the use of the instrument, as the operator does not have to spend time in ‘trialand- error’ method development.

High Throughput Rotors

Milestone offers a comprehensive selection of vessels, operating from low to high-pressure, in carousels simultaneously holding 8 up to 41 vessels.

High pressure

SK Rotor

SK-10/SK-12

SK-12 and SK-10 are specifically designed to provide chemists with incomparable performance capabilities and the highest standard of safety in closed vessel microwave digestion.
The high strength SK rotor body holds up to 12 digestion vessels made of high purity TFM, with a volume of 100 ml. These rotors ensure complete digestion of any sample, including relatively difficult organic and inorganic refractory materials.

Wide range of quartz, TFM, PFA vials also available with different volume size. They allow to reduce acids amount and contamination from the surface of sample vessels.

High versatility

Pro Rotor

The PRO-24 is a very versatile rotor, suitable for easy organic samples or environmental applications, according to the US EPA method 3051A. It offers very easy handling and rapid cooling capabilities.

High throughput

MultiPREP Rotor

MultiPREP

The MULTIPREP-41 is a very high throughput rotor holding TFM or PFA vessels, and can perform easy digestions or leaching-type reactions on a variety of samples, such as soils, sediments, wastewater etc.– according to the US EPA methods 3015a, 3051a and 3052 -, biological samples (tissues, food, feed, plants, agriculture products), and many others, such as paint chips and mineral leaches.
The MULTIPREP-41 combines the highest flexibility of operations with possibility to run up to 41 samples simultaneously: the highest sample throughput available from the market.

High purity

Q-20 Rotor

Q-20

The Q-20 rotor holds 20 high-purity quartz vessels and it offers superior performances, especially for ultra-trace analysis, with unmatched ease of use and full control of all digestion parameters in all vessels.
Minimal quantities of acid are needed, lowering the analytical blank. Just 3 ml of nitric acid are sufficient to digest 250 mg of organics!
The Q-20 allows for the complete digestion of a variety of organic samples, such as foods and feeds, plants, polymers, pharmaceuticals, clinical, biologicals and oils.

Reason Why

Superior digestion quality
Suitable for ultra-trace analysis
Lowest blanks: minimal quantities of acid are used for acid digestion
Lowest memory effect
Easy handling
Very rapid heating and cooling

High temperature

NOVA Rotor

NOVA-8

The NOVA-8 rotor holds 8 TFM vessels with a volume of 75 ml, and allows the digestion of ceramics and refractory materials; these samples often pose a challenge to users, as the very high temperatures and pressures required to digest them may result in damaging conventional pressure vessels or shortening their lifetime. The Milestone NOVA-8 rotor is especially designed to work at sustained high temperature up to 300°C, allowing for a safe and complete digestion of the most difficult matrices.

Reasons Why

Highest digestion temperature (300°C)
Highest stability at high temperatures
Improved components lifetime: the new high-performance polymeric materials resist to thermal softening and deformation.
Enhanced safety.

Automation

TWISTER:
Improving sample prep throughput

The new Milestone vessel handling module TWISTER is a step ahead toward automation in microwave digestion and it represents a perfect complement to the SK rotors.
The TWISTER eliminates the bottleneck associated with the handling of multiple digestion vessels, thus dramatically improving the sample preparation throughput.
Furthermore, it improves the overall quality of digestion, as it assures constant and reproducible closing of the vessels.
Finally, the TWISTER offers an increased safety of operation, as the operator is not exposed to acid vapors during the opening of the vessels.

For the MULTIPREP-41, Q-20 and PRO rotors a dedicated automatic capping/uncapping system is also available, THE ACM-100.
