Abstract:
Embodiments relate to a method and system for controlling a volume of liquid to be drawn and metered. One embodiment relates to a restraining divider for a syringe for controlling a volume of liquid drawn and metered by the syringe comprising a grooved side with a first groove and a second groove. Either the first groove or the second groove fits a shaft of a plunger of the syringe, wherein the length of at least one of the first groove, the second groove or the groove side provides a gap between a compressed thumb flange of said syringe and the body of the syringe.
