Dear Bumers:

We are in the process of buying some rotors for our CP/MAS Bruker
probe (Spinner: ZrO2, 7mm OD, Spectrometer: Bruker MSL-300). This is the
first time that we attempt to buy rotors. We have found three companies in
the market, Bruker, RotoTec and Cerobear. The prize of a rotor sells by
each company is quite different thought it seems they are offering the same
(or very similar) thing. Does any one know the differences between the
rotors sell by these companies?

Also, the cheapest is the one from Cerobear. Does any one have
experience with rotors from this company?

I would very much appreciate any information and or suggestion.

Thanks in advance for any help.
