Luer Lock Syringe Needles, 5pc/PK

Blunt-end needles with Luer Lock tip, used to connect a soft-walled tubing, such as silicone, Tygon, etc. to your microfluidic setup.  Luer Lock tip to ensure a safe and leak-free connection between a syringe and the needle.


In order to get better sealing and tighter connections, a needle with a slightly larger outer diameter (OD) than the tubing inner diameter (ID) should be used.


NOTE: It's NOT recommended to connect with rigid tubing (such as PTFE).
