Description
RN needle (22/51/3)L is a removable laboratory needle configured for controlled liquid handling and tissue injection. The (22/51/3) designation specifies a G22 outer diameter, a needle length of 51 mm and point style 3, giving a clear dimensional reference for method records and routine syringe work. Each multipack contains 6 pc(s), supporting repeated bench use without constant single-piece reordering. The RN (removable needle) hub format allows the cannula to be exchanged when required while remaining suitable for secure attachment during delivery. Gross pack weight is 0,024 kg, so the set stays compact for drawers, kits and shared workstations. Application data identify tissue injection as the primary use case, where consistent gauge and length help maintain reproducible handling. These needles from manufacturer Hamilton suit research, analytical and general laboratory environments that standardise on the classic gauge/length/point triad. The 51 mm working length combined with G22 geometry offers a practical balance of reach and handling stiffness for many injection and transfer steps. Point style 3 completes the specification for users selecting RN consumables by established dimensional codes.
This article is part of Needles & cannulas, in Syringes & needles.

Questions about RN NEEDLE (22/51/3)L 6/PK
What is this article?
RN NEEDLE (22/51/3)L 6/PK is the article on this page. Luminix Health distributes Hamilton for laboratory use. It sits in Needles & cannulas, inside Syringes & needles, in Consommables.
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.
