Description
SR N11-L is a transparent polyethylene snap-ring cap for N 11 vials, fitted with a white silicone / red PTFE septum. Septum hardness is 45° Shore A and thickness is 1,0 mm, giving a defined sealing and piercing profile for analytical work. The colourless PE shell includes a centre hole that allows syringe-needle access for injection or sample withdrawal. Packs of 100 pieces support continuous laboratory operation and high sample throughput. This N 11 snap-ring cap from manufacturer Macherey-Nagel is designed to mate with corresponding N 11 snap-ring vials used in chromatography. The dual-layer septum places elastic silicone toward the exterior and chemically resistant PTFE toward the sample side. Laboratories running HPLC or GC autosamplers that accept N 11 snap-ring formats can use these closures for routine sealing steps. The combination of PE cap, 45° Shore A silicone and 1,0 mm PTFE-faced septum provides a practical septum accessory among chromatography consumables for N 11 systems.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about SR N11-H, tr, Sil w/PTFE r, 45°, 1.0
What is this article?
SR N11-H, tr, 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.
