Butterfly Needles and Blood Collection Sets

A butterfly needle (winged infusion set) is a short needle with flexible plastic wings and a length of tubing. The wings make it easy to hold and position, so butterfly needles are widely used for taking blood from small, fragile or hard-to-reach veins, for children and older patients, and for short infusions. We stock butterfly needles and blood collection sets from BD, Terumo, B. Braun and Greiner Bio-One.

Blood collection sets

Blood collection sets such as the BD Vacutainer Safety-Lok, BD Push Button and Greiner VACUETTE safety sets have a Luer adapter or a pre-attached holder, so you can fill evacuated blood tubes directly. Infusion sets such as the Terumo Surflo and B. Braun Venofix are designed for giving fluids and medicines.

Gauge and safety

  • 21G (green): routine adult venepuncture
  • 23G (blue): smaller veins and most paediatric bloods
  • 25G (orange) and 27G: very small or fragile veins

Safety designs cover the needle after use, with a sliding shield (Safety-Lok) or a push-button retraction, to reduce needlestick injuries in line with the Sharps Regulations 2013. See our blood collection tubes and needles to complete your phlebotomy set-up.
