Abstract
A system and method for dispensing fluid including a pump having a stepper motor operably connected to a pump head. The pump head has an inlet and an outlet. The inlet is adapted to be in fluid communication to a fluid reservoir. A controller is operably connected to the motor. The controller drives the motor wherein a speed and an acceleration of the stepper motor is selected to overcome adhesion between the dispense tip and the dispensed fluid. A dispense tip formed of a hydrophobic material is in fluid communication with the outlet of the pump head.
