The Dynarex SecureSafe Syringes with Safety Needles provide a sterile, effective way to deliver comfortable injections. All needles are color coded to represent the gauge of the needle and attach to the syringe by either luer lock or luer slip connection. The needles have a double bevel, allowing for ease of penetration while reducing the required plunger force, helping larger doses flow smoothly. The SecureSafe safety mechanism features a quick cover that allows the user to cover and protect the needle with a press and snap. 8/100/CS
