Description
Screw cap N 9-L blue with silicone white/polyimide orange septum is a polypropylene closure for N 9 threaded vials used in analytical sample handling. The blue PP screw cap is centre-holed and fitted with a white silicone septum faced with orange polyimide. Septum hardness is 45° Shore A and septum thickness is 1,0 mm, giving a defined sealing stack for routine vial work. Supplied in packs of 100 pieces from manufacturer Macherey-Nagel, these caps suit N 9 autosampler and sample vials in chromatography and related laboratory workflows. The silicone layer provides the primary seal while the polyimide face adds a distinct barrier side for instrument use. Blue cap colour supports quick visual identification among mixed closure types on the bench. The combination of PP screw body, holed design and 1,0 mm dual-layer septum addresses everyday sealing needs for liquid samples prepared for GC or HPLC analysis without adding unnecessary complexity to vial preparation.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about SC N9-H, bl, Sil w/Polyimide or, 1.0
What is this article?
SC N9-H, bl, Sil w/Polyimide or, 1.0 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
A closure is the part that decides whether a bottle stays shut and whether the contents attack the seal. A ground-glass stopper matches a ground neck. A screw cap needs the right thread and a liner that survives the liquid. Rubber and silicone stoppers push into a mouth. The liner, not the colour of the cap, is the chemical choice. The vessels they close are indexed under ISO laboratory glassware.
