Description
Pre-sealed N 11 roll-neck vials with matching aluminium crimp caps provide a ready-to-use combination for chromatography sample preparation and storage. Each 1,5 mL amber glass vial has an outer diameter of 11,6 mm and an outer height of 32 mm, with a flat bottom, wide opening, labeling field and marking. The vials are already crimped with N 11 aluminium crimp caps in silver finish, fitted with a white silicone/blue PTFE septum that is cross-slit. Septum hardness is 55° shore A and septum thickness is 1,5 mm, supporting reliable needle penetration and resealing in GC and HPLC workflows. Brown glass helps protect light-sensitive samples while the wide-mouth geometry eases filling and transfer. Offered as a pack of 100 pieces from manufacturer Macherey-Nagel, this pre-assembled set (vial type 702892 with cap type 702823) reduces manual crimping steps and promotes consistent seal quality for routine analytical laboratories and automated sampling systems.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about Pre-sealed: 702892 + 702823
What is this article?
Pre-sealed: 702892 + 702823 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.
