Description
Screw cap SK N9-L is an N 9 polypropylene (PP) screw cap with a centre hole, finished in green for clear visual coding on laboratory benches and trays. Made for matching N 9 screw-neck vials, the open-hole design allows septum-based injection or sampling once a suitable liner is fitted, supporting liquid chromatography, sample storage, and general analytical workflows. Packs of 100 pieces come from manufacturer Macherey-Nagel for everyday laboratory use. Polypropylene offers a lightweight, practical closure for routine vial sealing where repeated access is needed. The green colour helps separate sample series, methods, or user groups at a glance and reduces mix-ups during multi-step preparation. As a screw rather than crimp closure, the SK N9-L format can be opened and resealed without specialised crimping tools. These caps fit standard N 9 thread systems common in HPLC and related sample-handling lines, giving organised, colour-coded consumables for chromatography and quality-control laboratories.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

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