Femtoliter to milliliter volumes of one or a plurality of different liquids are accurately dispensed electrokinetically without any direct electrical contact with such liquid(s). This is accomplished with apparatus which creates an electric field over dispensing receptacles to discharge such liquid(s) into receiver reservoirs or scientific apparatus. Two electrically-conductive plates are insulated from each other so that a field polarizes the liquid and forces movement without faradaic processes or joule heating. One of the plates is charged, whereas the other is grounded. Liquid to be dispensed is placed between the two plates and is dispensed on applying the charge to the charged plate.
