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


Our newly pioneered 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. With easyTEMP, every vessel becomes a reference and flexibility provided for digesting different matrices simultaneously.
