Description
SR N11-L is a soft N 11 PE snap ring cap in light blue, fitted with a centre hole and a red rubber/FEP colourless septum for reliable sealing of compatible vials in chromatography and general laboratory sample handling. The septum is specified at 45° Shore A hardness with a thickness of 1,0 mm, supporting consistent needle penetration and chemical resistance at the FEP contact face. Supplied in packs of 100 pieces, these caps suit routine workflows where snap-ring closure speed and reproducible septum performance matter. The light-blue PE shell makes the closure easy to identify on the bench while remaining soft enough for straightforward application. This configuration from manufacturer Macherey-Nagel is intended as a matching accessory for N 11 snap-ring systems used in analytical sample preparation and storage. Clear colour coding and defined septum geometry help laboratories standardise closures across series of samples without altering established vial formats.
This article is part of Vial caps & septa, in Vials, caps & septa.

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