Abstract
A hose assembly for use to regulate flow from a dispensing device that provides a generally constant pressure on a liquid to be dispersed. The hose assembly includes a length of capillary tubing through which the liquid must pass as it is dispersed which has a length of at least 45 centimeters and a volume of less than about 0.25 cubic centimeters so that the assembly can provide a slow steady predetermined flow rate while containing a small amount of the liquid being dispensed.
