I think a low-pH well buffer with volatile components (say (NH4)acetate )
would do the job, although I don't know about speed. Maybe you could
measure it with some old-fashioned pH sensitive dye in a trial drop?

Hi
Just a quick question.. for doign hanging drop, is there anyway that we
can decrease the pH of the drops on a (somewhat) controlled way, say over
a period of couple of weeks? Thanks
Andrew
