1. A method for aspirating a fluid from a source using an aspirate-dispense system including a drop-on-demand valve in fluid communication with a direct current fluid source, comprising the steps of:

  • reducing the hydraulic pressure within said system by opening said valve of said system to dispense system liquid into a non-target position;

    dipping a tube of said system in said fluid source; and

    creating a reduced pressure in said system to aspirate a quantity of said fluid of said source into said tube of said system.
