Manufactured from the highest purity Zirconia, our MAS Rotors provide the NMR spectroscopist with the ultimate alternative for analysis of solid samples; the need to solvate is eliminated. They are available for most present solid state NMR spectrometers.
Wilmad's MAS Rotors are carefully examined for material irregularities by optical methods before and after the precision machining process. Without over-spinning, each rotor is spin tested to only the highest specified spinning speed. Overspin testing, a common practice with some rotor brands, can actually damage the rotor prior to use. High precision (which becomes a necessity for proper spinning performance) is maintained in the manufacture of the end caps*. Most caps are fitted with O-rings for better sealing; some have axial holes for venting.
Advantages of Zirconia Rotors
Some of our caps have a uniquely designed detachable O-ring. Use it when a gas-tight environment is required for the sample.
