These SK N8-L open-hole screw caps from manufacturer Macherey-Nagel provide a consistent fit on compatible glass or plastic vials with the matching neck finish. The black colour supports clear visual organisation of sample sets and integrates smoothly into standard bench and autosampler workflows.

Questions about SC N8-H, blk
What is this article?
SC N8-H, blk 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.
