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. Wilmads 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:
• Most homogeneous ceramic material structure.
• Wilmads Zirconia Rotor Body has higher strength (1,000 MPa, greater than Si3N4).
• Highest spinning speed
• High precision superior finish (0.05 µ mirror gloss).
