1.9 mm MAS Rotor Kit

Solid-state Dynamic Nuclear Polarization (DNP) experiments are performed at low temperatures and require that microwaves can reach the sample substance with a minimum of attenuation. For 1.3 mm and 1.9 mm diameters, rotors made from zirconia can be used, but for DNP and for LTMAS applications, these should be selected as “tight-fit” variants. These are specially prepared rotor / cap pairs that maintain sample sealing and integrity on spinning in the ~ 95 K low temperature conditions of DNP and LTMAS.

The 1.9 mm Rotor kit includes:

• 1x zirconia through-bore rotor
• 4x drive Vespel caps
• 4x bottom Vespel caps
