Abstract
A syringe for dispensing medicaments or other materials includes a hollow syringe body having a discharge end portion and an open opposite end portion through which a plunger is slidably received. The plunger has a first end portion located within the syringe body and includes an integral seal forming a seal between the plunger and the interior of the syringe body. A removable length adjusting member is threadably engaged on the plunged outside of the syringe body to variably limit operating travel of the plunger in the syringe body, thereby to control the amount of material in the syringe body expelled therefrom upon depression of the plunger into the syringe body.
