An automatic microflow dispensing apparatus for dispensing small amounts of liquid at discrete time intervals, including a container for holding the liquid, and a dispensing element positioned on the container below the liquid level when the container is oriented to dispense the liquid. The dispensing element includes an air intake port and a liquid discharge port positioned below the air intake port when the container is oriented to dispense the liquid. These two ports are each in fluid communication with the container liquid. The vertical distance between the air intake port and the liquid discharge port defines a head which remains substantially constant during dispensing. The air intake port has a vertical height relative to the head sufficient to provide a predetermined microflow of the liquid.
