I have picked up several styles of syringes in the drug store, or the pharmacy department of larger stores.
Veterinary supplies are good, too. Ask at feed stores. People who keep horses, cattle and other large animals often do their own dog and cat vaccinations, and will use syringes for that. (I just saved them from the last time I vaccinated my dogs). Remove the needle (dispose of safely) and what is left is perfect for measuring small aquarium chemicals.
In drug stores, ask for children's dosing syringes. This is a measure up to 5 ml, graduated down to half ml. (Until the lines wear off)
Also look at eye droppers. Ask for them as eye droppers, they will know what you mean. The ones I have measure 1 ml, graduated to .1 ml.
Some are not graduated. Ask, or shop elsewhere.
