Description
SR N11-L is a soft, light blue polyethylene (PE) snap ring cap for N 11 vials, featuring an open-top design and a white silicone / blue PTFE septum with cross-slit. Septum hardness is 55° Shore A and septum thickness is 1,0 mm, supporting consistent sealing during sample storage and injection. Each pack contains 100 pieces for everyday laboratory replenishment. The PTFE layer forms the chemical-contact surface while silicone provides elasticity and reseal after needle passage; the cross-slit aids penetration and reduces coring tendency. The soft light blue PE shell distinguishes this variant on the bench and fits standard N 11 snap-ring neck geometry. Offered by manufacturer Macherey-Nagel, this cap suits chromatography and general analytical workflows that call for PE snap closures with silicone/PTFE septa. Specify it when a soft light blue N 11 snap ring cap with a 1,0 mm, 55° Shore A cross-slit silicone white/PTFE blue septum is required for routine sample handling and autosampler use.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about SR N11-H, lbl,s,Sil w/PTFE bl (+),55° 1.
What is this article?
SR N11-H, lbl,s,Sil w/PTFE bl (+),55° 1. 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.
