Hydraulically and volumetrically dispensing a target fluid

A target fluid dispenser comprising:

• a hydraulic coupler that includes a first hydraulic liquids, a master piston and a slave piston, wherein the hydraulic coupler is a closed-loop system;
• a first driving mechanism configured to create a force to selectively actuate the master pistons, wherein the first driving mechanism is coupled to the hydraulic coupler;
• and
• a first container configured to contain a first target fluid separate from the first hydraulic liquid, wherein the first container is coupled to the hydraulic coupler and selectively dispenses a known volume of the first target fluid upon actuation of the master piston.

A method for volumetrically dispensing target fluid, the method comprising the steps for:

• providing a first target fluid in a dispenser;
• containing a hydraulic liquid separate from the first target fluid;
• selectively engaging a master piston to create a force on the hydraulic liquid;
• transferring the force on the hydraulic liquid to a slave piston;
• and
• using the slave piston to dispense a known volume of the first target fluid.

A method as recited in claim further comprising the steps for:

• providing a second target fluid;
• containing a second hydraulic liquid separate from the second target fluid;
• selectively engaging a second master piston to create a force on the second hydraulic liquid;
• and
• transferring the force on the second hydraulic liquid to a second slave piston;
• using the second slave piston to dispense a known volume of the second target fluid.
