ABSTRACT:
The present invention is a system for dispensing a precise quantity of liquid. The liquid dispensing system is composed of a rigid first tube and a nozzle secured to the first tube. The first tube terminates at a mating surface and is aligned and immobilized by a support stand. The nozzle has a channel extending therethrough, a barb, a first extension extending from the barb to terminate at a mating surface, and a second extension extending from the barb to terminate at a tip. The mating surface of the nozzle makes a conforming fit with the mating surface of the first tube when in an engagement position thereof, whereby the nozzle and the first tube are stationary and aligned relative to each other. A flexible second tube, which is in communication with a liquid source, is connected to the barb of the nozzle. The flexible second tube delivers liquid to the nozzle which travels through the channel in the nozzle and is dispensed from the liquid dispensing system to a substrate located at a constant distance from the tip of the nozzle.
