Description
SK N9-kL N 9 PP screw cap, blue and closed, with virgin PTFE white septum is a laboratory closure for N 9 short-thread vials. The septum hardness is specified at 53° Shore D with a septum thickness of 0,25 mm, giving a defined sealing profile for sample containment. Polypropylene construction of the blue closed cap supports routine handling in analytical sample preparation and storage. Pack size is 100 pieces, suited to continuous laboratory throughput where consistent N 9 closures are required. This configuration from manufacturer Macherey-Nagel combines a closed screw-cap body with a white virgin PTFE liner for a clean contact surface. The thin 0,25 mm septum and Shore D hardness rating help users match the closure to method needs involving pierceable or non-pierceable sealing practices on N 9 vials. Categories cover screw closures and original-style caps used across general laboratory workflows. Net and gross pack weight is 0,03 kg per unit pack, reflecting a compact consumable format for chromatography and related sample-handling benches without added sterility claims.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about SC N9-nH, bl, PTFE w, 53°, 0.25
What is this article?
SC N9-nH, bl, PTFE w, 53°, 0.25 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.
