Description
neochrom® aluminium crimp caps ND11 with hole and silicone/PTFE red septum are chromatography closures designed for ND11 vials used in GC and HPLC. Colourless-lacquered aluminium shells incorporate a 5,5 mm centre opening and a pre-assembled silicone/PTFE septum with a thickness of 1,3 mm. The silicone/PTFE laminate withstands temperatures from −60 °C to +200 °C and is specified for single-injection use, offering a broad thermal window for demanding analytical conditions. This configuration suits methods that require a clean puncture path and a chemically resistant barrier between sample and atmosphere. Packed as 100 pieces and available from manufacturer neolab - Labor, the neochrom® ND11 crimp caps support standardised sample preparation and instrument loading in analytical laboratories. They integrate with conventional crimping tools and vial systems, making them a practical choice for single-shot injections in research, quality control, and routine chromatographic workflows where temperature range and septum integrity are critical selection criteria.

Questions about neochrom® Capsules à sertir en aluminium ND11 avec trou, septum silicone/PTFE rouge, 100 pièces
What is this article?
neochrom® Capsules à sertir en aluminium ND11 avec trou, septum silicone/PTFE rouge, 100 pièces is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Bouchons de vials & septa, inside Vials, bouchons & septa, in Chromatographie.
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.
