Description General description These polypropylene syringes with Luer tips, may be used with any size needle. The rigid polyethylene plungers of these disposable syringes are slightly oversized, creating a tight seal against the walls of the semi-flexible PP barrel, as well as providing an exceptionally smooth draw. No contaminating lubricants added. Syringes are individually packaged (sterile) except for bulk packed products; these are supplied in plastic bags (non-sterile). Order needles separately.
