What is the difference between luer lock and luer slip syringes?

Syringes are available in a wide variety of forms for different applications. A question we get asked a lot is “What is the difference between Luer Lock and Luer Slip syringes?”

Luer lock syringes

The Luer fitting is a standardised system across small-scale fluid fittings in order to make leak-free connections between two parts. These are common across medical and laboratory instruments. They are described as having a male-taper fitting and its mating female part.

Syringes are one of the most common instruments using the luer fitting system with the male luer connection fitting the female needle which either screws into it or fits tightly on top. These can be split into two varieties by the connection type: locking or slipping.

The locking ‘Luer-Lok’ style are more secure, the needles are inserted into the syringe and twisted to form a locked connection; ensuring no liquids can leak and prevents accidental removal of the needles.

The slipping ‘Luer-Slip’ style are quicker to fit, requiring a simple push of the needle into the syringe and ready to go. Luer-slip syringes can also be called ‘luer fitting’ syringes.
