Abstract
A system and method is provided which substantially eliminates the effect of air entrapped in tubing for delivering a liquid from a container. The inner diameter of the tubing is selected such that the gravitational force of the liquid from the container is greater than the surface tension of the liquid. A release agent may be used as a coating layer on the interior wall in addition to or alternatively from an expanded diameter.
