Description
N 11 aluminium crimp cap in silver finish with centre hole combines a robust metal shell with a white silicone/blue PTFE septum that is cross-slit for controlled needle entry. Septum hardness is 55° Shore A and septum thickness is 1,5 mm, supporting dependable sealing on compatible N 11 vials used in chromatographic sample handling. The dual-layer liner pairs the elasticity of silicone with a PTFE contact face oriented toward the sample, helping maintain chemical resistance during GC and HPLC workflows. Cross-slitting facilitates autosampler penetration and can reduce septum coring under repeated injections. Offered by manufacturer Macherey-Nagel as a chromatography accessory, the cap is intended for routine laboratory sealing where consistent crimp performance and defined septum geometry matter. Pack size is 100 pieces, convenient for method development, quality control and high-throughput sample series. Dimensions and materials follow the stated N 11 aluminium crimp design with silver appearance, holed shell and silicone/PTFE cross-slit septum at the given hardness and thickness.
This article is part of Vial caps & septa, in Vials, caps & septa.

Questions about CC N11-H, si, Sil w/PTFE bl (+) 55°, 1.5
What is this article?
CC N11-H, si, Sil w/PTFE bl (+) 55°, 1.5 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.
