A system for storing and delivering a predetermined amount of fluid, the system comprising: (a) a syringe defining a longitudinal axis, comprising: (i) a barrel comprising: a first end, a second end, and a lumen extending between the first and second ends, (ii) a first flange disposed at the second end and extending away from the longitudinal axis, and (iii) a plunger assembly configured to be received in the lumen of the barrel and move relative to the lumen to draw fluid into and dispense fluid from the syringe, wherein the plunger assembly comprises: a piston, a plunger rod comprising a first end and a second end, wherein the first end of the plunger rod is coupled with the piston, wherein the plunger rod comprises a second flange at the second end of the plunger rod; (b) a first spacer, wherein the first spacer is configured to restrict advancement of the plunger assembly relative to the barrel to prevent the plunger assembly from advancing beyond a first predetermined distance from either a portion of the first flange or a portion of the barrel; and (c) a second spacer, wherein the second spacer is configured to restrict advancement of the plunger assembly relative to the barrel to prevent the plunger assembly from advancing beyond a second predetermined distance from either a portion of the first flange or a portion of the barrel and thereby prevent the plunger assembly from advancing to said first predetermined distance; wherein the first spacer is removably couplable to at least one of the barrel, the first flange, or the plunger assembly, and the second spacer is removably coupleable to the first spacer, wherein the first and second spacers (1300, 1400) are configured to nest with each other and with the syringe such that the second spacer fits around the first spacer. (a) a syringe defining a longitudinal axis, comprising: (i) a barrel comprising: a first end, a second end, and a lumen extending between the first and second ends, (ii) a first flange disposed at the second end and extending away from the longitudinal axis, and (iii) a plunger assembly configured to be received in the lumen of the barrel and move relative to the lumen to draw fluid into and dispense fluid from the syringe, wherein the plunger assembly comprises: a piston, a plunger rod comprising a first end and a second end, wherein the first end of the plunger rod is coupled with the piston, wherein the plunger rod comprises a second flange at the second end of the plunger rod; (i) a barrel comprising: a first end, a second end, and a lumen extending between the first and second ends, a first end, a second end, and a lumen extending between the first and second ends, (ii) a first flange disposed at the second end and extending away from the longitudinal axis, and (iii) a plunger assembly configured to be received in the lumen of the barrel and move relative to the lumen to draw fluid into and dispense fluid from the syringe, wherein the plunger assembly comprises: a piston, a plunger rod comprising a first end and a second end, wherein the first end of the plunger rod is coupled with the piston, wherein the plunger rod comprises a second flange at the second end of the plunger rod; a piston, a plunger rod comprising a first end and a second end, wherein the first end of the plunger rod is coupled with the piston, wherein the plunger rod comprises a second flange at the second end of the plunger rod; (b) a first spacer, wherein the first spacer is configured to restrict advancement of the plunger assembly relative to the barrel to prevent the plunger assembly from advancing beyond a first predetermined distance from either a portion of the first flange or a portion of the barrel; and (c) a second spacer, wherein the second spacer is configured to restrict advancement of the plunger assembly relative to the barrel to prevent the plunger assembly from advancing beyond a second predetermined distance from either a portion of the first flange or a portion of the barrel and thereby prevent the plunger assembly from advancing to said first predetermined distance;
