Description
N 13 PP screw cap, black and closed, with Red Rubber/FEP colourless septum is a precision closure component for laboratory sample vials and chromatography workflows. The polypropylene cap carries a bonded septum of Red Rubber laminated with colourless FEP, specified at 45° Shore A hardness and 1,5 mm septum thickness for reliable resealing and chemical resistance during repeated needle penetration. Supplied in packs of 100 pieces, these closed screw caps support secure sealing of N 13 neck vials in analytical chemistry, quality control and routine sample storage. The combination of a rigid black PP shell and the Red Rubber/FEP liner helps maintain sample integrity while offering a chemically inert contact surface toward many organic solvents. Designed for everyday laboratory use, the closure format from manufacturer Macherey-Nagel fits standard N 13 thread geometry and is intended as a ready-to-use consumable for GC, HPLC and general lab sample handling. Consistent hardness and septum thickness support reproducible piercing behaviour across the pack, making the product suitable for high-throughput environments where dependable vial sealing is required.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about SC N13-nH, blk, RR or/FEP,45.°, 1.5
What is this article?
SC N13-nH, blk, RR or/FEP,45.°, 1.5 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.
