Abstract

A precision syringe includes a syringe barrel and plunger that has a base, an internal portion, and an external portion. The internal portion of the plunger extends longitudinally into the syringe barrel. The internal portion has a first end coupled to the base and a second end that is configured to push fluid out of and/or suction fluid into the syringe barrel. The external portion extends longitudinally along an outer surface of the syringe barrel. The external portion has a first end coupled to the base and a second end that is configured to receive an applied force that causes the plunger to move relative to the syringe barrel so that the second end of the internal portion is actuated through a portion of the syringe barrel (e.g., to dispense fluid from or suction fluid into the syringe barrel).
