Description
N 11 aluminium crimp cap BK N11-L is a silver crimp seal with centre hole and a white virgin PTFE septum for chromatography sample handling. The septum hardness is specified as 53° Shore D with a septum thickness of 0,25 mm, supporting reliable needle penetration and resealing in routine GC and HPLC workflows. Designed for N 11 crimp-neck vials, the aluminium shell provides a secure mechanical closure while the pure PTFE liner offers broad chemical compatibility for many organic solvents and aqueous matrices. Supplied in packs of 100 pieces from manufacturer Macherey-Nagel, this accessory suits laboratories that standardise on N 11 formats and need consistent septum performance without multi-layer laminates. The open-hole design allows direct septum access for autosampler or manual injection. Use these caps wherever a simple virgin PTFE barrier and defined Shore D hardness are required for analytical sample preparation and storage on the bench or in automated systems.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about CC N11-H, si, PTFE w, 53°, 0.25
What is this article?
CC N11-H, si, PTFE w, 53°, 0.25 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.
