A syringe stroke controlling mechanism includes a gripping member encircling a syringe barrel and a cap on the plunger of the syringe. A spring urges the plunger outwardly of the barrel and a metering rod couples the cap to the gripping member. Adjustment of the metering rod sets the maximum separation permitted between the plunger cap and the gripping member and thereby controls the stroke of the syringe plunger.
