Dear all,

=20

We have a Varian 4 mm ghx Nanoprobe (purchased around 2000, the "older"
version, using smooth brown rubber as the driver ring). We have been
using the glass rotor well. I recently started a new project which may
require much higher spinning speed than 2.5 kHz (the safety limit for
the glass rotors, I assume). While contacting Varian for answers, I also
want to know if anyone out there knows whether compatible faster rotors
exist and if it does exist, where to get them and how reliable they are.
I would like to reach a spin rate at least to 5 kHz so that I can spin
the sideband out on my 500M.=20

Any suggestions are highly appreciated.=20
