There's no need to create one - standard fluids exist for the purpose.
Here's one source, another may be the maker of your refractometer.

Or, if you are really cheap, take your refractometer to a honey
show, and calibrate it against one of the honey judges.

Once calibrated, I paint some red fingernail polish over the
adjustment screw to eliminate any possible bumping, and act
as a "calibration seal".  This worked great with my old Atago,
but I have not owned my new one long enough to know if it will
stay within calibration for a season.  So far, so good...
