Description
SK N9-L is a blue polypropylene (PP) screw cap with hole for N 9 threads, supplied in a practical pack of 100 pieces. The open-top design with a central aperture is intended for use with septa on sample vials, allowing syringe access while the cap remains screwed in place. Made from PP, the closure combines chemical resistance with the mechanical stability needed for routine laboratory handling and storage of vials. The blue colour supports quick visual identification on the bench or in sample trays. This N 9 screw cap format is widely used in chromatography, sample preparation and general analytical workflows that rely on standard narrow-neck vials. Offered by manufacturer Macherey-Nagel, the SK N9-L blue perforated screw caps arrive ready for pairing with compatible septa and N 9 vials. The pack quantity of 100 pieces suits both daily laboratory consumption and stock replenishment. Net weight of the pack is 0,02 kg, reflecting a lightweight, easy-to-store consumable for screw-closure applications.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about SC N9-H, bl
What is this article?
SC N9-H, bl 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.
