Description
SK N9-L is an N 9 polypropylene screw cap with centre hole, finished in red and fitted with a silicone white/PTFE red septum. Hardness is specified at 45° Shore A with a septum thickness of 1,0 mm, giving a controlled seal for analytical vial work. Each pack contains 100 pieces, making the closure convenient for continuous use with N 9 screw-neck vials in chromatography, autosampling and everyday laboratory sample handling. The polypropylene shell ensures a secure screw fit, while the PTFE-lined silicone septum is intended to support chemical resistance and clean needle passage through the open top. This red SK N9-L version from manufacturer Macherey-Nagel helps laboratories apply simple visual coding when several sample series run in parallel. The centre aperture allows syringe access without removing the cap, which is useful in both manual and instrument-based workflows. Combining a defined septum stack, stated Shore hardness and a practical pack quantity, the product offers a straightforward N 9 open screw-cap solution for routine sealing and injection tasks in analytical laboratories.

Questions about SC N9-H, r, Sil w/PTFE r, 45°, 1.0
What is this article?
SC N9-H, r, Sil w/PTFE r, 45°, 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.
