Service and Support

Rototec-Spintec has a service facility based in Bad in  Germany, to supply service and support for all products we supply. 
Another aspect of Rototec-Spintec's service activities is the repair or upgrading of NMR probes of most types and manufacturers, including adaptation to enable a NMR probe from one manufacturer to be re-used on another manufacturer's NMR system.

Spinner Turbines

We supply the most common 5 mm and 10 mm Spinner Turbines for Agilent (Varian)- , Nalorac- and Bruker NMR-Probes. 
Spinner Turbines are manufactured to precision standards that meet or exceed those of the spectrometer manufacturers. 
A new 5mm PEEK version for Varian Spectrometers with superior VT performance and magnetic susceptibility has now also been released, as well as a POM based RT version for high throughput sample changers. 
The POM Spinner Turbine for Bruker Spectrometers incorporates two O-rings for ease-of-use and snug fit on the sample tube. The POM Spinner Turbines for Bruker Spectromters can also be used in high field NMR spectrometers.

Doty Scientific Probes

Doty Scientific with over 30 Years od Experience in NMR Probes & MRI Coils for Varian, Agilent, Bruker, Jeol, Tecmag and other System.

Doty supporting the NMR/MRI researcher with custom probe development expertise and the best solids NMR and MRI-RF products in the industry. 

For over 30 years Doty have been the major force in the advance of solids probe technology, with dozens of ‘firsts’ in CP/MAS, including multi-nuclear, narrow-bore, triple-resonance, 500 MHz, SAS, 750°C, 26 kHz, 15 Kelvin, and 600 MHz. 

Many of these products include air-bearing-supported micro-turbine-driven all-ceramic sample spinners capable of achieving supersonic surface speeds.
