Histonetters,
>From my old days of doing titrations in analytical chemistry lab, I learned that a
"drop" is approximately 50 microliters. This is a real ballpark figure; depends
on delivery tip, ambient breezes, method of delivery, etc. So we always take
those darn lids off the Vector bottles, and use 10 microliters of A and B per mL.
Works great. Saves reagents. We can stain a 10-20 embryos using 100 microliters
of ABC reagent.

For those prefering to pipette rather than squeeze, I suppose that you
could use a good balance & a known volume from a well calibrated pipette to
determine volume per drop.
--just an idea.
Thanks for all the great discussions & advice.
