SK-12
Medium pressure segmented rotor
The SK-12 is specifically designed to provide chemists with incomparable performance capabilities and the highest standard of safety in closed vessel microwave extraction.
The SK-12 is a medium pressure segmented rotor containing 12 vessels for the solvent extraction of several organic compounds from sample such as soil, sludge, sediments, wastewater, food and feed, plastic, etc..

-
SK-6 Large Volume
Large volume segmented rotor
 The SK-6 is a large volume segmented rotor which contains six vessels for the solvent extraction of several organic compounds from large amount of samples such as soil, sludge, sediments, wastewater, food and feed, plastic, etc..
Milestone patented SK-6LV provides analysts with unsurpassed performance capabilities and the highest standard of safety in closed vessel solvent extraction.
The extraction vessels have no molded or machined threads to be chemically attacked and weakened by hot vapors during vessel venting and opening: this boosts durability and safety of Milestone extraction vessels.

PRO-16 ad PRO-24
Medium Pressure High Throughput Rotors
The PRO system has been designed for increasing the sample throughput in modern analytical laboratories. PRO-16 and PRO-24 offer you the greatest number of full sized 75 mL TFM microwave vessels available. This enables you to simultaneously process up to 24 liquid or solid samples using established microwave methodologies.
Reasons Why
- Precise temperature monitoring directly on sample
- High pressure conditions can be reached
- Easy Handling of PRO reactors.
- Flexibility: possibility of choosing between either the 16-position rotor or a full set of 24.
- Rapid air or water cooling: this increases your sample turnaround and lengthens the vessel’s working lifetime.

Multiprep-41
High Throughput Rotors
 The Milestone MULTIPREP-41 is a new high throughput rotor, suitable for the microwave solvent extraction of any sample requiring moderate temperature and pressure conditions for a full recovery of the analytes of interest.
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.
Reasons Why
- Unsurpassed ease of use
- No tools for capping/uncapping
- Easy samples weighing and vessels cleaning
- Direct and external temperature control with individual temperature profiles
- Temperature homogeneity across vessels
- Pressure control in all vessels

Q-20 Quartz Rotor
Superior Extraction Quality and Sample Throughput
 The new Milestone Q-20 Quartz rotor truly opens a new era in microwave extraction, and is a fundamental addition to the outstanding capabilities of the ETHOS One and the START E units.
The Q-20 offers elevated performance specifically for ultra-trace analysis, unsurpassed ease of use, and full control of all extraction parameters in all vessels. This rotor holds up to 20 high-purity quartz vessels, minimizing acid diffusion through the vessels walls and in turn contamination and memory effect.
Reason Why
- Superior extraction quality
- Suitable for ultra-trace analysis
- Lowest memory effect
- High sample throughput: up to 20 samples per run
- Easy handling
- Very rapid heating and cooling
- Full control of all extraction parameters (temperature, pressure) and complete documentation
The new Q-20 Quartz rotor is the perfect compliment to highly sensitive analytical instruments, such as GC, GC-MS, HPLC and other analytical techniques.
The START E labstation
Post-Extraction Solvent Evaporation
With Milestone’s unique vacuum evaporation technology, the START E microwave units turn into a true microwave evaporator, allowing the user to carry out safe and complete evaporation of acids and organic solvents. No sample transfer is required, as the evaporation takes place in the same vessels previously used for digestion and extraction.

Vacuum Evaporation
The MMR rotor is a device for conveniently heating materials in a microwave field under controlled vacuum conditions. When connected to an external vacuum supply (VAC-1000 or VAC-2000 modules), and depending on the specific configuration, the MMR rotor can be used for vacuum assisted sample drying, acid removal, volume reduction, and solvent evaporation.
The Advantages of the Milestone MMR Technology
- Low temperature, safe evaporation and concentration of acids and organic solvents.
- No sample transfer: evaporation takes place in the same vessel used for digestion.
- Evaporation of polar and non-polar organic solvents (e.g. Hexane) after organic solvent extraction.
- Rapid evaporation and concentration: 200 mL of acids (HC1, HF, HN03, etc.) evaporated in 30-90 minutes.
- Sample drying before extraction or digestion.
- Available as an eight (8) or twelve (12) position fixture.
- Accommodates all Milestone's TFM vessels of all digestion rotors.
Automation
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.
TWISTER and ACM-100 Benefits:
- Automatic opening and closing of Milestone vessels
- Simple and fast operation
- Reduction in vessels handling
- Reproducible operations
- Higher productivity and sample throughput
- Adjustable opening speed for highest safety
Tedious and timeconsuming operations are eliminated!
