Description
SK N24-kL is a white, closed polypropylene (PP) screw cap for laboratory vials and bottles with an N 24 neck finish. The solid, non-perforated top provides a reliable seal for sample storage, transport and general handling where access through a septum is not required. Each pack contains 100 pieces, supporting efficient restocking of consumables in analytical, quality-control and research laboratories. Polypropylene offers practical chemical resistance for many routine aqueous and organic workflows when used with compatible vessels and threads. These closures from manufacturer Macherey-Nagel are intended as matching N 24 screw caps to help maintain sample integrity during short- and medium-term storage on the bench or in racks. The white colour improves visual identification among mixed laboratory hardware. Typical uses include chromatography sample preparation, environmental sampling kits, wet-chemistry protocols and everyday vessel sealing where a closed screw closure is preferred. The compact pack format suits both high-throughput laboratories and smaller workgroups that need dependable N 24 PP screw caps ready for immediate use.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about SC N24-nH, w
What is this article?
SC N24-nH, w 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.
