Description
ND24 polypropylene screw cap is a white, closed laboratory closure fitted with a 2,5 mm butyl red/PTFE grey septum for sealing matching ND24 screw-neck vials and bottles. The closed PP shell protects the liner and provides a uniform grip surface for manual or routine laboratory capping, while the red butyl face bonded to grey PTFE forms the sample-contact septum stack. A septum thickness of 2,5 mm suits standard pierceable access in analytical sample preparation and storage workflows that specify butyl/PTFE liners. Supplied in a pack of 1000 pc(s), the caps are practical for continuous bench use and instrument sample series. This screw cap from manufacturer Altmann Analytik is positioned as laboratory consumable hardware for ND24 systems requiring a white closed PP lid with butyl red/PTFE grey. Colour contrast between the white cap, red butyl, and grey PTFE helps staff verify liner type during setup of environmental, chromatographic, or general analytical sample trains without altering the stated product geometry or materials.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about ND24 PP screw cap, 2,5mm, 10 x 100 pc
What is this article?
ND24 PP screw cap, 2,5mm, 10 x 100 pc is the article on this page. Luminix Health distributes Altmann Analytik 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.
