Which syringe type allows for the needle to screw onto the tip?

The Luer-Lok tip syringe is designed with a threaded connection that allows the needle to be securely screwed onto the tip of the syringe. This feature is particularly beneficial in veterinary pharmacology and other medical fields as it reduces the risk of the needle detaching during use, ensuring greater safety and accuracy when administering medications.

In contrast, the slip-tip syringe has a smooth, friction-fit end where the needle simply slips on, which may not provide the same level of security as the Luer-Lok design. The catheter tip syringe, while useful for specific applications like delivering fluids through a catheter, also does not use a screw mechanism. The insulin syringe typically has a fixed needle that cannot be removed or replaced; it is specifically designed for administering insulin doses and does not feature a threaded connection. The distinguishing feature of the Luer-Lok syringe makes it essential in situations where a stable and secure attachment for the needle is necessary, enhancing the overall efficiency and safety of drug administration.
