N 8 PP screw cap, black, closed, with red rubber/FEP colourless septum provides a solid, non-pierced closure for laboratory sample vials. The polypropylene cap is fully closed and lined with a dual-layer septum of red rubber bonded to colourless FEP. Specified hardness is 45° Shore A and septum thickness is 1,3 mm, supporting dependable sealing for storage, transport and handling of liquid or volatile samples. Delivered in packs of 100 pieces, these caps are appropriate for chromatography sample preparation, quality-control aliquots and general laboratory use where needle access is not required. The FEP face offers chemical resistance toward many organic solvents, while the rubber backing maintains elasticity and compression set performance. This closed N 8 configuration from manufacturer Macherey-Nagel is intended for matching N 8 screw-thread vials and gives a clear black exterior for quick identification on crowded benches and in automated sample racks.

Questions about SC N8-nH, blk, RR or/FEP,45.°, 1.3
What is this article?
SC N8-nH, blk, RR or/FEP,45.°, 1.3 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Schroefdoppen & sluitingen, inside Stoppen, doppen & sluitingen, in Labmateriaal.
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.
