Description
Pre-sealed N 11 roll neck vials of 1,5 ml capacity combine amber glass bottles with factory-crimped aluminium seals for ready-to-use chromatography and sample-storage applications. Each assembly pairs a brown 1,5 ml roll neck bottle—outer diameter 11,6 mm, outer height 32 mm—with a flat bottom, wide opening, writing field and marking, already crimped to an N 11 silver aluminium cap. The centre-holed cap carries a natural rubber/butyl red-orange septum laminated with colourless TEF; septum hardness is 45° Shore A and thickness is 1,0 mm. Supplied as a pack of 100 pieces from manufacturer Macherey-Nagel, these pre-crimped units reduce preparation time and improve seal consistency versus manual capping. Amber glass helps protect light-sensitive samples, while the wide-mouth geometry eases filling and septum access for autosampler or manual injection workflows. The combination suits HPLC, GC and general analytical sample handling wherever N 11 roll neck compatibility and a reliable butyl/TEF barrier are required in a ready-crimped format.

Questions about Pre-sealed: 702892 + 70256
What is this article?
Pre-sealed: 702892 + 70256 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Vial caps & septa, inside Vials, caps & septa, in Chromatography equipment.
A vial cap and a septum have to match the vial neck: crimp, screw or snap, and the diameter. The septum material, PTFE/silicone or rubber, decides chemical resistance and how many times a needle can pierce it. A septum that sheds into the solvent becomes ghost peaks.
An autosampler vial is the small closed bottle a chromatograph picks up. The neck is crimp, screw or snap, and the cap and the septum have to be that neck. The septum is the part the needle pierces. A soft septum reseals. A septum that is wrong for the solvent swells or sheds particles into the sample. Inserts reduce the volume when the sample is scarce. The separation they feed is described with IUPAC names and PubChem data.
