Description
N needle (20/51/5) is a laboratory needle specified for septum-piercing applications in analytical and sample-handling work. It combines a G20 outer diameter with a 51 mm needle length, giving a defined geometry for controlled passage through septa while retaining mechanical stability in routine use. The (20/51/5) designation identifies the gauge, length and tip configuration commonly selected for this type of piercing task. Supplied as a pack of 6 pieces, the needles are practical for laboratories that need consistent dimensional reference across multiple instruments or workstations. From manufacturer Hamilton, the N needle format supports integration into syringe, autosampler or manual sampling setups where a G20, 51 mm needle is required. Typical use includes access to sealed vials and other septum-closed vessels in research, quality control and analytical chemistry environments. Clear gauge and length data help match the needle to existing protocols and hardware without ambiguity about outer diameter or working length.
This article is part of Needles & cannulas, in Syringes & needles.

Questions about N NEEDLE (20/51/5) 6/PK
What is this article?
N NEEDLE (20/51/5) 6/PK is the article on this page. Luminix Health distributes Hamilton for laboratory use. It sits in Needles & cannulas, inside Syringes & needles, in Lab consumables.
A needle or a cannula is specified by gauge, length and point, and by how it connects, Luer or cemented. A blunt needle is for transfer. A sharp needle is for piercing. Gauge is the outer diameter: a higher gauge is a thinner needle. The fitting has to match the syringe.
A syringe is a barrel and a piston. A disposable syringe is for transfer and injection. A microlitre syringe is a precise analytical tool, often with a cemented or removable needle, used to inject into a chromatograph. The needle gauge and the point, and the Luer or cemented connection, have to match the job. A Luer slip and a Luer lock are not the same fitting. In-vitro and diagnostic context is under ISO in vitro diagnostic systems.
