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. General 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.

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.   Content 100x Blunt-end Luer Lock needles Specifications Material Polypropylene (Luer Lock tip) Stainless steel (needle) Needle length 0.5 in. / 1.27 cm Color 32G: Yellow 30G: Purple 27G: Clear 25G: Pink 23G: Orange 22G: Blue 21G: Violet 20G: Cream 18G: Green 16G: Grey 15G: Brown Sizes 32G: 0.11 mm ID / 0.23 mm OD 30G: 0.16 mm ID / 0.31 mm OD 27G: 0.21 mm ID / 0.42 mm OD 25G: 0.26 mm ID / 0.51 mm OD 23G: 0.33 mm ID / 0.63 mm OD 22G: 0.41 mm ID / 0.70 mm OD 21G: 0.51 mm ID / 0.83 mm OD 20G: 0.62 mm ID / 0.90 mm OD 18G: 0.84 mm ID / 1.27 mm OD 16G: 1.32 mm ID / 1.60 mm OD 15G: 1.37 mm ID / 1.65 mm OD
