Tips:
- These needles are mostly used to connect a 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), and is not recommended.
- You should choose a needle with a slightly larger outer diameter (OD) than your tubing inner diameter (ID) to ensure a tight connection.
