Description
SK N9-L N 9 polypropylene screw cap is a black open-top closure fitted with a Red Rubber/FEP colourless septum for analytical vial sealing. Septum hardness is 45° Shore A and septum thickness is 1,0 mm, supporting consistent needle penetration in chromatography and routine sample handling. The PP shell with dual-layer septum combines elastomeric resealing with an inert FEP contact face on N 9 thread vials. Packs of 100 pieces from manufacturer Macherey-Nagel suit GC and HPLC preparation where reproducible septum behaviour is required. Black colour coding helps organise sample sets on the bench, and the open-hole design lets autosampler needles pierce cleanly while the Red Rubber/FEP laminate protects the sample interface. These caps integrate into existing N 9 vial systems without changing thread geometry. Gross and net pack weight are each 0,03 kg. The product is a standard laboratory accessory for chromatography consumables and general analytical workflows requiring dependable screw-cap closures.

Questions about SC N9-H, blk, RR or/FEP, 45°, 1.0
What is this article?
SC N9-H, blk, 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.
