Systems and methods for hydraulically and volumetrically filling and dispensing target fluid. A hydraulic system comprises an actuator, a hydraulic coupler that includes substantially incompressible hydraulic liquid, and a target fluid container. The actuator includes a motor or driver, such as a step motor, linear actuator, servomotor, pneumatic motor, or other similar device, to selectively drive a piston of the hydraulic coupler. The coupler includes a conduit, column, shaft or other leak proof assembly that acts as a conduit for the substantially incompressible hydraulic liquid and includes a cord and a piston, which is selectively pushed by the incompressible hydraulic liquid, thereby driving a plunger to selectively press against a slidable wall of the target fluid container, causing the target fluid to be dispensed therefrom, or retract the plunger from the container, pulling the slidable wall therewith through the use of a vacuum selectively created between the plunger and the wall. Furthermore, the system may include a controller that is configured to control the target fluid dispensed and to receive input from a user.
