And if you are near a pharmacy (Chemist's, to you Brits!), you can get
plastic droppers, measured in ml, for a lot less. And, unless you are using
organic solvents to which the plastic may be reactive, they not only are as
good as glass pipets, but better, as they have an opening to measure exactly
15 drops per ml. (Incidently, all my scientific catalogs show "pipet" as the
correct spelling. This was a surprise to me, as I've always previously
spelled it "pipette." Gotta keep up with the times.)
