Best case, it would depend on what kind of probe you have. If your
probe contains the same type of solution it might be fine, but if not,
I doubt it would be a good idea!

Many people say that 7.0 buffer (calibration) soln is the next best
thing -- I would use that until I can get my hands on some proper
storage soln.
