The present disclosure relates to a syringe including a container, for containing a primary fluid, and at least one secondary fluid chamber configured to contain a secondary fluid. The container comprises a proximal end and a distal end and having a distal end opening at the distal end. The syringe further comprises a stopper, movably arranged within the container; and a plunger engageable with the stopper and configured to apply a force to the stopper to move the stopper within the container towards the distal end of the container, to expel primary fluid from the container through the distal end opening. The plunger is further configured to expel secondary fluid from the at least one secondary fluid chamber towards the distal end opening, to expel at least a portion of a residual volume of primary fluid through the distal end opening. A plunger system and assembly for a syringe and methods of expelling fluid from a syringe are also disclosed.
