Abstract
Under a reduced-pressure environment, stopping at will liquid that flows out from a nozzle tip, or dispensing liquid with the level of energy at which it will not splatter has proven difficult. To address such difficulties, parameters including nozzle bore, and surface tension and viscosity of, and delivery pressure on, a liquid are selected so that the surface tension that acts on the liquid when flowing out from the nozzle tip will be greater than the momentum of the liquid. By dispensing liquid under such conditions, outflow of the liquid is reliably controlled, and rapid infusion work is realized.
