Description
KF Needle (18/51/5) is a laboratory cannula with outer diameter gauge G18 and a needle length of 51 mm, offered as a pack of 6 pieces. The 18/51/5 coding defines gauge, length and tip style for reproducible septum work in analytical chemistry and sample preparation. Designed for piercing septa, it enables clean entry through vial caps, bottle closures and sealed reaction vessels when a medium-fine G18 profile is preferred. The G18 outer diameter offers a balance between rigidity and reduced septum coring risk compared with larger gauges, while the 51 mm length reaches typical laboratory septa and sampling ports. These characteristics make the needle suitable for chromatography-related sampling, titration support and general liquid or headspace handling after septum penetration. Supplied from manufacturer Hamilton, the needles arrive as a matched set of six, helping laboratories keep instruments and methods aligned on the same gauge and length. Consistent geometry across the pack supports repeatable piercing performance in routine and method-driven workflows.
This article is part of Needles & cannulas, in Syringes & needles.

Questions about KF NEEDLE (18/51/5) 6/pk
What is this article?
KF NEEDLE (18/51/5) 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.
