Q-20 Quartz Rotor

Superior Digestion Quality and Sample Throughput

Q-20 The new Milestone Q-20 Quartz rotor truly opens a new era in microwave digestion, and is a fundamental addition to the outstanding capabilities of the ETHOS 1 and the START D units.
The Q-20 offers elevated performance specifically for ultra-trace analysis, unsurpassed ease of use, and full control of all digestion 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.
It allows the complete digestion of a variety of organic samples, such as food and feed, plants, polymers, pharmaceuticals, clinicals, 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
High sample throughput: Up to 20 samples per run (Only 3 ml of acid to digest 250 mg of organic samples!)

Unsurpassed Ease of Use
The Milestone MultiFAST-4 allows the operator an easy and safe handling as it does not require the use of any gas.

Evaporation Concentration

Vacuum Evaporation

With Milestone’s unique vacuum evaporation technology, the ETHOS One and START D 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.
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.
This unique design provides an ideal platform for predigestion of large quantities of organic materials in near atmospheric conditions, followed by closed vessel digestion at elevated temperature.

Protein Hydrolysis

Protein hydrolysis

The ETHOS 1 enables vapor phase protein hydrolysis within 30 minutes in inert, anaerobic conditions, without thermal degradation of the amino-acids, or cross contamination of the solutions. All vials are loaded in a single operation with minimal handling required.
This assures a substantial time reduction over conventional methods, which often require up to 48 hours.
All samples are processed under equivalent temperature conditions avoiding possible variations between samples and assuring precision of result.

MOD-8 Open Vessel Digestion rotor
