Re: [?? Probable Spam] Cleaning 2.5 SSNMR rotors

Hello,

I have seen someone of the MPI institution, which has done a measurement
of molted polymers
via MAS. He has cooled down the rotor with polymer in liquid nitrogen
and then pushed the
polymer out with a needle like a cork of a wine bottle.

I'll hope this treatment helps you a bit.

Yours
