When creating drops two features become important. 1. diameter of orifice. 2. Angle of dropper as one holds it. A 45 deg angle creates a larger drop than a vertically held dropper. Be consistant when holding the dropper.
Regarding Kelly's post above and drop dilutions, are you familiar with use of serial dilutions?
