Description
Snap ring cap SR N11-L is an N 11 polyethylene snap-ring closure with centre hole, finished in red and fitted with a Red Rubber/FEP (colourless) septum. Septum hardness is 45° Shore A and septum thickness is 1,0 mm, giving a balanced seal for routine chromatographic sample vials. Packaged in units of 100 pieces and offered by manufacturer Macherey-Nagel, these caps are intended for matching N 11 snap-ring vials in HPLC and related analytical workflows. The PE shell allows quick push-on attachment without threading, while the dual-layer rubber/FEP liner supports chemical resistance on the sample side and reliable resealing after needle penetration. The 45° Shore A rating indicates a relatively soft elastomer suited to autosampler injection. Consistent 1,0 mm septum thickness helps maintain reproducible penetration behaviour across a pack. Laboratories specifying N 11 snap-ring geometry can use this combination for standard sample storage, transport and instrumental analysis.

Questions about SR N11-H, r, RR or/FEP, 45°, 1.0
What is this article?
SR N11-H, r, RR or/FEP, 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.
