Description
N 8 aluminium crimp cap in silver finish is an open-top closure for chromatography sample vials. It combines a centre hole with a white silicone/red PTFE septum rated at 45° Shore A hardness and a septum thickness of 1,0 mm, giving a defined sealing interface for routine analytical work. The aluminium shell provides a stable crimp geometry for N 8 neck finishes, while the dual-layer liner supports needle penetration and chemical contact on the PTFE face. Packaged as 100 pieces, this configuration from manufacturer Macherey-Nagel suits HPLC and GC sample preparation, storage, and injection workflows where consistent septum performance is required. Laboratories can integrate the cap into standard crimping procedures for high-throughput vial handling without changing established N 8 hardware. Clear colour coding of the silicone/PTFE layers aids visual identification on the bench. As chromatography accessory hardware, it addresses everyday sealing needs for analytical vials that rely on aluminium crimp closures and resilient septa of defined hardness and thickness.

Questions about CC N8-H si, Sil w/PTFE r, 45°, 1.0
What is this article?
CC N8-H si, Sil w/PTFE r, 45°, 1.0 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.
