Description
BK N11-L, si is an N 11 aluminium crimp cap in silver finish with a centre hole, intended as chromatography vial closure accessory. The open-hole design allows septum access for injection while the aluminium shell supports a firm crimp seal on matching N 11 neck vials used in GC and HPLC sample handling. Packed in units of 100 pieces, the cap suits routine analytical throughput where consistent sealing of autosampler or storage vials is required. Its silver aluminium construction is a standard choice for laboratory crimp closures that must remain dimensionally stable under normal bench and instrument conditions. From manufacturer Macherey-Nagel, this BK N11-L, si variant addresses everyday needs in chromatography accessory sets for method development, quality control and high-sample-series work. Laboratories can integrate the holed silver N 11 crimp caps into existing vial workflows without changing neck size, relying on the familiar Bördelkappe format for secure, injection-ready closures. The 100-piece pack keeps consumable stock practical for continuous analytical operation across research and routine testing environments.

Questions about CC N11-H, si
What is this article?
CC N11-H, si 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.
