Unisharp 1ml fixed needle syringe, with a 27G needle, teal green plunger and needle cap.
Unisharp 1ml fixed needle syringes are used for injecting water soluble drugs. The 27G needle is slightly thicker and stronger than the 29G and 30G needles, and is mainly used for injecting drugs into veins, especially where there is scar tissue which makes injecting with thinner needles difficult.
