Description
N 13-L polypropylene screw cap, black, with centre hole is a laboratory closure for N 13 screw neck vials. The open-hole design is intended for use with septa, enabling syringe access, sampling and injection steps typical of chromatography and analytical sample handling. Black PP provides a lightweight, durable cap body suited to repeated bench handling and clear visual sorting among mixed closures. Matching the N 13 thread standard, the cap seats on compatible screw neck vials used throughout sample preparation and storage chains. Packaged as 100 pieces, it supports efficient stocking for multi-sample series and routine laboratory operations. This N 13-L screw cap with hole from manufacturer Macherey-Nagel is a practical accessory wherever pierced closures are specified for manual or automated needle access. The black colour and polypropylene construction suit everyday analytical workflows that rely on a consistent N 13 open-top format. Use it with matching N 13 vials when a holed screw cap is required for sealed yet accessible samples.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about SC N13-H, blk
What is this article?
SC N13-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.
