temperature calibration

I need to do a variable temperature experiment where
I know the temperature quite accurately. I have some
charts from an old Bruker manual that give the chemical
shifts of 100% methanol and 100% ethylene glycol versus
temperature. Does anyone know how robust these calibrations
are? In particular, is the calibration thrown off by a
bit of moisture in the solvent, picked up from the air?
I noticed that Wilmad sells sealed tubes of these
solvents which they call chemical shift thermometers.
Does this imply that one needs to take a lot of care
when preparing these standards?
Thanks
