Description
N 11 aluminium crimp cap BK N11-L is a blue open-top aluminium crimp seal for laboratory vials that need a stable septum interface. The cap incorporates a central hole and a colourless red rubber/FEP septum. Hardness is rated at 45° Shore A and septum thickness at 1,0 mm, supporting reproducible needle penetration while the FEP face limits direct contact between the rubber layer and the sample. Supplied in packs of 100 pieces, the closures fit chromatography, quality-control and general analytical routines that standardise on N 11 neck-finish vials. Blue colour coding makes it easy to distinguish sample groups, instrument queues or method streams on the bench and in autosamplers. Aluminium crimp construction ensures a tight mechanical seal after application with a compatible crimper. These caps from manufacturer Macherey-Nagel form part of the widely used N 11 crimp-cap programme for pharmaceutical, environmental and research laboratories. Gross and net pack weight are each 0,03 kg. Select this blue BK N11-L option when you require open-top aluminium crimp caps with red rubber/FEP liners at 1,0 mm thickness together with clear visual sample coding.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about CC N11-H, bl, RR or/FEP, 45°, 1.0
What is this article?
CC N11-H, bl, 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.
