These needles with a blunt-end tip are particularly useful in microfluidics, avoiding any cutting of the tubing or injuries while working with syringe pumps or microfluidic Luer connections. The Luer Lock tip ensures a safe connection between a Luer Lock port (syringe, stopcock...) and the needle.
Available in various gauges, with a needle length of 0.5" (12.7 mm).
Pack of 100 needles.

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.
