Where can I buy the sugar water that Docs dip pacifiers into for soothing newborns?

I'm trying to get my 3 month old to take a pacifier and the only time he has taken one was when he was in the hospital and they dipped his pacifier in some sugar water. I'm flying on a VERY long flight and would like to bring some with me in case he starts screaming. Does anyone know where I can buy the little containers they have in the hospital, or even what it is called?
