Blunt-end Luer Lock Syringe Needles (pack of 100)

A pack of 100 blunt-end needles for general lab use.

90° cut, avoiding any injuries or tubing cutting while working with needles in microfluidics (e.g. for syringe pumps).
Luer Lock tip to ensure a safe and leak-free connection between a syringe and the needle.
Nonsterile
Needle length: 0.5" / 1.27 cm
Available in various gauge sizes:

Tips:

These needles are mostly used to connect soft-walled tubing (such as silicone, Tygon...) to your microfluidic setup. The connection will be less tight and effective with rigid tubing (such as PTFE), though it can be used as a cost-effective alternative to threaded fittings.
You should choose a needle with a slightly larger outer diameter (OD) than your tubing inner diameter (ID) to ensure a tight connection.
