The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). The experiment entailed observing tiny electrically charged droplets of oil located between two parallel metal surfaces, forming the plates of a capacitor.
Bio-oil 7, which was more stable than bio-oil 1 in the foam test, was much more sensitive to mineral oil in the filter test. A 2-percent contamination with common hydraulic fluid A resulted in progressive filter clogging.
