Abstract
A programmable electronic fluid dispenser with computer controlled direct drives of a motor, connecting rod, and attached piston in a yringe is used to dispense accurate quantities of liquids with varying viscosities. The pistons are driven to dispense an amount and then the piston is reversed, overcoming any mechanical backlash, to prevent any leakage or oozing from the dispenser tip. A computer controls several dispensers cwith their outputs co-mingled. The desired proportions controlled by the computer driving the pistons.
