Description
Screw cap N9-L is a colourless polypropylene N 9 screw closure with centre hole, fitted with a Red Rubber/FEP septum for reliable sealing of compatible N 9 screw-neck vials. The septum combines red rubber with a colourless FEP layer, hardness 45° Shore A and septum thickness 1,0 mm, supporting needle penetration while limiting sample interaction at the contact face. Transparent PP construction keeps the cap visually discreet on the vial and simplifies identification of the underlying septum stack. Packaged as 100 pieces, the open-top design is intended for chromatography and general analytical sample work where repeated or automated access through the septum is needed. Matching N 9 thread geometry helps ensure a secure fit on corresponding screw vials used in routine LC and GC sample preparation. This closure from manufacturer Macherey-Nagel provides a practical combination of PP cap and Red Rubber/FEP liner for laboratories standardising on N 9 screw systems. Suitable for everyday vial sealing where a 1,0 mm, 45° Shore A RR/FEP septum is specified.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about SC N9-H, tr, RR or/FEP, 45°, 1.0
What is this article?
SC N9-H, tr, RR or/FEP, 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.
