Revolution NMR manufacture and service wide bore solid state NMR probes and consumables.
TalaveraScience is the sales agency for Revolution NMR throughout Europe.
Revolution NMR has a wide range of solid state NMR products ranging from:
- standard and custom wide bore HX, HF, HFX and HXY MAS probes;
- static eFree probes;
- static eFree probe consumables;
- PENCIL rotor consumables from complete rotor assemblies to rotor parts, such as, drive caps, end caps, bottom caps and sample confinement systems;
- sample packing tools;
- high pressure MAS rotors (200 bar);
- PENCIL spinning modules for probe repairs and for home builds;
- Revolution NMR provides service for Chemagnetics and early Varian solid state NMR probes.
Revolution NMR has also, in collaboration with Bruker BioSpin, developed the Agilent to Bruker (A2B) programme which allows the continued use of Chemagnetics, Varian and Agilent PENCIL MAS NMR
probes when replacing consoles to the latest Bruker NMR instrument offering. This allows the spinning speed control and, in some cases, variable temperature control by the Bruker BioSpin environmental
Revolution NMR works in close collaboration with Phoenix NMR and provides rotor parts for each of Phoenix NMR's probes.

The Revolution NMR probes depicted to the left are a DAS NMR probe and to the far right, a 4 mm MAS NMR probe.
Revolution NMR Solids NMR Data...
The two spectra depicted above are results from a Revolution NMR 3.2 mm double resonance (HX) MAS NMR probe installed on a Bruker BioSpin 500 MHz NMR spectrometer measuring 133Cs
NMR of 133CsCl(aq) at 1 M concentration.
The spectrum above left demonstrates the nutation curve for 133Cs and its correspomding lineshape is demonstrated in the image depicted above right.
The image depicted below left is of the 11B nutation curves on 1 M aqueous solution of H3BO3.
The 17O MQMAS NMR spectrum depicted bottom right is of the glass with composition 80% SiO2, 10% K2O, 10% PbO enriched to 80% with 17O acquired with MAS
rates of 17 kHz.

Revolution NMR High Pressure Solid State MAS NMR
High pressure MAS NMR using standard Chemagnetics, Varian, Agilent and Revolution NMR probe technology: Second Generation High Pressure MAS Technology.
The patented second generation high pressure magic angle spinning technology design developed by the team led by David Hoyt and Eric Walter are exclusively licensed to Revolution NMR from Battelle
Memorial Institute as operator of the Pacific Northwest National Laboratory (PNNL).
Their design eliminates the need for the large pressure chamber in the original design achieving rotor pressures up to 300 bar and temperatures from -150 to 250° C can be achieved through a modified rotor and
a set of o-rings along with a pressure source and a simple tool set.
The figure depicted below left demonstrates the assembly sequence of the rotor and the 13C MAS NMR spectra below right demonstrates temperature variation of the ethylene glycol at pressure.
The figure to the right is of the transparent schematic view of the high pressure
PENCIL MAS NMR rotors.
The high pressure MAS rotors are available in 5 mm and 7.5 mm diameters for Chemagnetics,
Varian, Agilent and Revolution NMR probes. The 5 mm rotor is rated at 5 kHz spinning speed at maximum pressure,
while the 7.5 mm rotor is rated to 3 kHz. High speeds are possible at lower pressures.
The figure above shows the components of the high pressure rotors and the tools for these including packing the rotor. The High Pressure Transporation Chamber (HPTC) is a vital safety component for transporting
packed and pressurised rotors. The user will need to ensure they have enough HPTCs for the number of pressurised rotors they envisage
they will be using at any one moment.
Below is a figure of the simple pressurisation chamber consisting of pressure tubing and unions. The simplest version requires the packed rotor to be placed in the tube and the end cap tightened on. A more sophisticated
version can use a ball valve which gives a quick access to the pressurised rotor. All you need to do is open the valve - place the rotor through the valve into the tube, close the valve and then pressurise the rotor.
On completion, return the chamber to atomospheric and open the valve and tip to remove the rotor. remember to place the pressurised rotor into the

Revolution NMR Agilent to Bruker Conversion Program
By the timeof the exit of Agilent Technologies from the NMR market, several solid state NMR groups have accumulated a large number of Chemagnetics, Varian and Agilent MAS NMR probes representing
significant value. Bruker BioSpin and Revolution NMR have collaborated to produce a kit that allows these probes to be used directly on Bruker NMR spectrometers allowing them to be controlled
by the Bruker spinning speed controller and, where appropriate, the Bruker VT controller.
One kit is required per spectrometer and comes in two parts:
- the MAS A2B electric adapter which allows the Bruker MAS controller to communicate with the tachometer and control spinning;
- the variable temperature A2B components which include adapter plates to mount probes to Bruker shim coils, mechanical adapters for the VT-transfer stack,
mechanical adapters for the Johnstone coupling, interface boxes to run the VT stack (NB, please do not dispose of your VT stack, however, Revolution NMR do make heater stacks!).
A checklist is completed to ensure that compatibility is achieved.
The A2B kit is produced and serviced by Revolution NMR. This can be purchased directly from Bruker BioSpin or Revolution NMR (through TalaveraScience in Europe).
Revolution NMR Rotors, Spinning Modules and Probe Service
Rotors and Rotor Components
Revolution NMR provides PENCIL MAS rotors for 1.6 mm, 2 mm, 2.5 mm, 3.2 mm, 4 mm, 5 mm, 6 mm, 7 mm, 7.5 mm, 9.5 mm and 14 mm spinning systems. We have a wide range of variants available for most of the
rotors including thin-walled version, sapphire, low-Al zirconia and cavern-style rotors as well as the high pressure MAS rotors discussed earlier.
Revolution NMR has methods to constrain liquid samples or air sensitive samples in the MAS rotors including ampules at 6 mm and end and top caps that seal to the rotor sleeve for a wide range of rotor
Revolution NMR manufactures a full range of sample packing tools with the following features:
- the rotors are held securely over the full length of the rotor eliminating the possibility of mishandling, loss and breakage;
- the packing tool is accurately aligned with and matched with rotor ID ensuring proper packing without rotor damage;
- the cleaning tool is designed to fully remove the sample without damage to the inside of the rotor;
- separate tools for easy and safe removal of the top and drive caps;
- are available in a variety of sizes to fit all standard solids PENCIL rotors
- complete operating instructions are available on the Revolution NMR website;
- and are compatible with all Chemagnetics, Varian, Agilent and Revolution NMR rotors.
Revolution NMR offers cost effective solid state NMR probe service for Chemagnetics and older early Varian probes (newer Varian and Agilent solid state NMR probe service is offered by Phoenix NMR).
Revolution NMR works with you to identify the most cost effective method to get your probe back up and running again.
Services offered, but not limited to, include all spinning problems, crashed rotors, broken RF traps and other probe issues.
