SK-10 & SK-12 Medium/High Pressure Rotors

These segmented-type rotors are designed to the highest safety standards and offer unmatched performance for difficult samples requiring high pressure and temperature. Heavy duty rotor construction and TFM vessels.  Vessel size: 100mL. Accepts microsampling inserts for handling of small samples and for ultratrace analysis.

The SK-10 is a high pressure rotor that holds 10 samples and the SK-12 is a medium pressure rotor that holds 12 vessels. The flexibility and wide application coverage of the SK rotors makes them the most commonly used rotors with the ETHOS EZ.

Venting technology: Milestone patented Vent-and-reseal

Specifications:

Max. temp. 300°C, Max. pressure 100 bar (SK10)
Max. temp. 300°C, Max. pressure 35 bar (SK12)

Typical application: Suitable for every application up to and including difficult organic materials such as hydrocarbons and polymers, and refractory inorganic materials.

Q-20 Quartz Rotor Ultratrace Analysis, High Sample Throughput

Another Milestone first in rotor design is the new Q-20 Quartz rotor, which holds 20 high purity quartz vessels. The Q-20 is most suited to ultratrace analysis since quartz has the lowest possible blank contamination and because the shape of the vessel allows the amount of digestion acid to be reduced, which minimizes the reagent blank level. In addition, with quartz, acid diffusion through the vessel walls is eliminated, which prevents any possible memory effects. 

Q-20 vessels are very easy to use, and heat and cool rapidly.  All vessels have indirect temperature control via IR sensor, and since quartz is transparent and has excellent heat conduction properties, IR temperature feedback is very fast, eliminating the need for direct temperature control.  

Venting technology: Milestone patented Vent-and-reseal

Specifications: Max. temp. 250°C, Max. pressure 40 bar

Typical application: Medium pressure capability enables application to a very wide variety of samples, such as environmental, foods, plants, polymers, pharmaceuticals, clinical, biological and oil samples, provided no HF is used in the digestion. Producing the lowest possible reagent blank levels, the QP-20 is especially suited to ultratrace measurement with ICP-MS.

PRO-16 & PRO-24 Medium Pressure, High Throughput Rotors

The PRO system uniquely combines medium pressure with high throughput and can hold up to 24 75mL TFM vessels. The PRO vessels are very easy to handle: capping is by hand with no tools needed, and an indicator in the cap confirms the cap has been tightened correctly. The rotor’s flexible design allows both a 16 and 24 position capacity.  The PRO rotor has a max. pressure of 30 bar, which means it meets the pressure requirements of US EPA methods 3015A, 3052 and 3051.

Venting technology: Milestone patented Vent-and-reseal

Specifications: Max. temp. 260°C, Max. pressure 30 bar

Typical application: High throughput labs running environmental and organic samples. The medium pressure capability of the PRO rotor is a benefit for samples such as soils and sludges, while its higher capacity compared to the 10 or 12 position high pressure rotors makes it more productive.

NOVA-8 High Temperature Rotor

Another example of Milestone’s leadership in rotor technology is the NOVA-8 high temperature rotor, which is able to withstand extremely high temperatures - up to 280°C - for long periods, allowing for the complete digestion of the most challenging samples.

The NOVA-8 holds 8 vessels and combines breakthrough twin shielding vessel technology (ceramic and high-performance polymer shields) with a construction optimized for free air flow and fins for optimum cooling. An innovative external safety shield improves insulation, further enhancing the overall safety of the system while new, high-performance polymeric materials resist thermal softening and deformation, extending vessel lifetime. The NOVA-8 was the first ever rotor capable of digesting refractory samples.

Venting technology: Milestone patented Vent-and-reseal

Specifications: Max. temp. 300°C, Max. pressure 100 bar

Typical application: Very difficult inorganic materials such as silicon carbide, metal oxides, geological, and refractory materials.

MultiPREP-41 High Throughput Rotor

The Multiprep-41 is a very high capacity rotor that can hold up to 41 sample vessels and is suitable for the digestion of most sample types. Vessels are capped by hand and are easy to clean.

MultiPREP-41 vessels have self regulating pressure control, not Vent-and-reseal. Compared to Vent-and-reseal, self-regulating vessels do not control overpressure situations as effectively, so sample weight should be limited to 0.2g and fat content to ,25%.  MultiPREP can digest up to 41 samples simultaneously-however with any very high capacity rotor, there are limitations on the sample types that can be digested in large batches.

Venting technology:  Self-regulating

Specifications: Max. temp. 260°C, Max. pressure 30 bar

Typical application: Low pressure digestion or leaching of a variety of samples including environmental and foods to US EPA methods 3051a and 3052, chemical and biomedical. Full capacity can only be used with easy to digest samples, or low sample weight/sample volume.
