Description
N needle (21/51/2) is a laboratory needle intended for gas chromatography (GC) injection. It is specified with an outer diameter of gauge G21 and a needle length of 51 mm, corresponding to the (21/51/2) designation of this N-type format. The product is supplied as a pack of 6 pieces, giving analytical laboratories a matched set of needles for routine sample introduction. Gross weight of the pack is 0,044 kg. Clear gauge and length data support method documentation, instrument setup and consistent handling in GC workflows where reproducible needle geometry is required. These needles from manufacturer Hamilton are positioned for GC injection use in research and quality-control environments that rely on defined needle dimensions. The G21 outer diameter and 51 mm length provide a straightforward dimensional reference when selecting consumables for chromatographic systems. Offered as 6 pc(s), the pack format suits laboratories that run multiple GC instruments or replace needles at regular intervals. Country of origin is Romania. Together, the gauge, length, application focus and pack quantity help purchasing and laboratory teams identify the correct N needle variant for GC injection tasks.

Questions about N Needle (21/51/2) 6/pk
What is this article?
N Needle (21/51/2) 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.
