Luer-lok syringe

From Biology-Online Dictionary
Jump to: navigation, search



A glass syringe with a simple lock mechanism to secure needle in place during injections


Luer-lok syringe has a locking mechanism to ensure that the needle is secured in place. The needle needs to be twisted to fix it upon the barrel. This feature is lacking in Luer slip wherein the needle only need to slide to fit to the barrel. Thus, Luer-lok syringe is safer to use for hypodermic and intravenous injections.

Word origin: from its German medical instrument maker, Hermann Wülfing Luer (18th century)

  • Luer's syringe
