Needles and Syringes

• Luer Lock Syringe offer a more secure connection. Luer lock syringes need a needle to be twisted on and locked in place. This helps prevent accidental slipping and the needle from falling off.
• Luer Slip Syringes offer a quick and simple way to attach a needle. This type of syringe is cheaper and better for quick injections. Luer slip needles can sometimes pop off and are why some medical professionals prefer to use a luer lock syringe.
• Catheter Tip Syringes are commonly used for injecting through the tubing, or when a regular slip tip needle is larger than a normal slip tip. Eccentric tip syringes have an off-center tip and are commonly used for surface veins or artery injections.
• Insulin Syringes typically come with a needle attached. They have a short thin needle to help prevent pain and bruising. The barrel of an insulin syringe is long, thin, and is marked in units of insulin. The size of the syringe varies by how much fluid you need to use and by the injection you will be doing. Syringes are marked in cubic centimeters (cc) and milliliters (ml) and are marked on the barrel of the syringe. The graduations on an insulin syringe show the number of units it holds and is not always displayed in cc or ml. For example, A 1/4 ml insulin syringes will hold approximately 25 units, 1/3ml will hold approximately 30ml. ½ ml insulin syringe will hold approximately 50 units, 1ml syringe will hold approximately 100 units of insulin.
