you are right the bottles will not hold 9cc. what I did was the following.
I emptied a bottle of BA and used this one to mix. I measure 8 cc and put them in my empty bottle, then I draw 1 cc to mix in my gh bottle. Becareful not to shake or point directly at the gh and don't jam the water in there. I always did it slow and against the bottle. I had read that GH is very delicate so you must not shake it and be gentle with it.
Maybe this was a little over the top, but when you spend this kind of cash in my opinion its better safe then sorry.
Where ever you ordered your pinz, and ba from they should have sterile empty vials also that you can use.
Good luck!
