Need more? The Milestone ETHOS UP isn’t just intelligent, it’s the most powerful microwave digestion system on the market today. Featuring the highest throughput rotors, stainless steel construction and patented vent-and-reseal technology, the ETHOS UP ensures market-leading safety and productivity. Very smart.

Superior Flexibility

Three distinctly different rotors make ETHOS UP the most flexible system available.

  • SK-15 high-pressure rotor is suitable for even the most challenging applications.
  • MAXI-24 HP high-performance rotor delivers both high-throughput and high temperature/pressure capability in a single, easy-to-use solution.
  • MAXI-44 high-throughput rotor for more routine applications including environmental and clinical.

The SK-15, MAXI-24 HP, and MAXI-44 rotors all feature Milestone’s patented ‘vent-and-reseal’ technology (US Patent 5,270,010), which safely regulates the pressure of all vessels, while minimizing the loss of volatile elements.

Our pioneering easyTEMP direct contactless temperature sensor combines the use of infrared and in-situ temperature sensors to provide superior digestion quality, direct temperature control of all vessels and enhanced ease-of-use.

SK-15 High Pressure Rotor

The SK-15 is a high-pressure and high-temperature rotor featuring up to 15 TFM vessels with a volume of 100 mL and suitable for all applications. It ensures high quality digestion of even the most difficult and reactive samples, such as polymers, pharmaceuticals, alloys, geological materials and large sample amounts of food and feed with high fat content.

  • High versatility and flexibility
  • High productivity even for challenging samples
  • Inherent ease of use

MAXI-24 HP High Performance Rotor

The MAXI-24 HP is a high-performance rotor, designed to process increased volumes of sample types and weights within a single rotor-based platform.  That means you can focus on what counts: increased throughput, high-quality data, and more profitable runs.

  • High-performance and throughput in a single rotor
  • Achieve higher temperatures and pressures than possible with traditional high-throughput rotors
  • Unmatched ease-of-use with simple 3-component vessel design

MAXI-44 High-Throughput Rotor

The MAXI-44 is a high-throughput rotor featuring up to 44 TFM vessels with a volume of 100 mL and suitable for a wide range of samples such as clinical, environmental and food. It is perfect for routine applications, as it combines unmatched ease of use with the highest sample turn-around-time available today from the market. The MAXI-44 complies with commonly used standard methods, such as the US EPA 3015, 3051, and 3052.

  • Unparalleled batch samples productivity
  • User friendly setup with only three components
  • Large volume, suitable for high volume digestions
Rugged, Reliable Construction

Milestone has been at the forefront of advanced microwave sample preparation since 1988. Over the years, we have continuously developed our technology with safety in mind, such as with the introduction of an all stainless-steel door in 1993 and self-resealing safety door in 1996. The new ETHOS UP is specifically designed for intensive laboratory use and offers the perfect integration between microwave hardware, user interface, reaction sensors and pressure vessels. While other manufacturers use molded plastic, Milestone uses 18/8 stainless steel construction throughout which creates the most durable, reliable, and heavy-duty microwave system available.

Intuitive User Interface

The ETHOS UP is controlled via a compact terminal with an easy-to-read, bright, full-color, 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 Milestone’s renowned EasyCONTROL software, a completely new user-friendly, icon-driven, multi-language and CFR-21 Part 11 compliant software to provide easy control of the microwave run. Simply recall a previously stored method or create a new one; by pressing ‘START’, the system will automatically follow the user defined temperature profile using a sophisticated PID algorithm. As a visual aid for the user, the color of the backlit logo indicates the status of the sample preparation process (stand-by, heating, cooling, ready). Hundreds of applications, including all US EPA methods, are preloaded in the ETHOS UP terminal, virtually eliminating any need for method development. Each method includes temperature profile, sample size and choice of reagents. There is no need to input the number of samples, as the software will automatically regulate the microwave power accordingly. This assures a consistent quality of the digestion and simplifies the instrument’s use.

Accessory Options

A number of accessories are available to help the analyst get the most out of the ETHOS UP. Milestone offers a variety of inserts in different materials (Quartz or TFM) and with various sizes and shapes, accommodating a vast array of applications.

Both quartz vessels and insert options are available for the SK-15 and MAXI-44 rotors. Quartz is the ultimate vessel material for ultra-trace analysis, since it can be cleaned more effectively, and has lower background levels than even extra high purity TFM.

Optional inserts, available in quartz and high purity TFM, fit inside the standard TFM vessels of the high pressure SK-15 rotor, expanding the application range of the ETHOS UP beyond any other microwave system.

Tap Into Unlimited Resources

ETHOS UP users get access to a groundbreaking web based application – Milestone Connect. Milestone Connect provides up to date information and extended instrument control from outside the laboratory. With the ability to remotely monitor every sample in real time, achieving superior digestion quality is enhanced. Users also have the ability to remotely stop the run – a great safety feature. Milestone Connect 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 an online help section that provides instant support available 24 hours a day, 7 days a week.
