This would allow avoiding contaminating the
jar. I'd like to find a plastic/rubber-bulb dropper that would hold
maybe 2cc's at a time, but so far all I have found has not been suitable
for this use. Any ideas?

To my knowlege, toluene will not attack virgin polyethylene.

There are numerous "disposable" laboratory eye droppers made from blow-
molded PE.
