The Dynarex Syringes without Needle can be used with any size needle with either a luer tip or luer lock connection. These syringes offer a full range of clear barrel syringes featuring easy to read markings, giving an excellent view of the contents for precise dosing and readability. With wider unit spacing, the users can draw up to an accurate dose of medication between 1cc and 60cc. The Dynarex Syringes have a smooth-gliding integrated plunger, helping prevent the plunger from being pulled out, as well as providing exceptionally smooth draw.
