Description
neochrom® PP screw closures ND10 are black polypropylene screw caps with a 10-425 thread and a 7 mm centre hole, fitted with a silicone white/PTFE red septum for single-injection laboratory use. Designed for ND10 vial formats, they provide straightforward needle access through the open-hole cap while the dual-layer septum supports sealing during routine sample introduction. Temperature resistance spans −60 °C to +200 °C, allowing use from cold storage through elevated analytical conditions typical of chromatography workflows. Each pack contains 100 pieces, making the closures practical for batch sample preparation, autosampler loading and everyday analytical work. The red PTFE face paired with white silicone distinguishes this septum variant and suits laboratories that standardise on colour-coded closures. Offered in the neochrom® range from neolab - Labor, these ND10 screw closures match common 10-425 threaded vials used in pharmaceutical, environmental and research settings. Select this open-hole PP cap with silicone white/PTFE red septum when a clear, single-injection ND10 sealing option is required.

Questions about neochrom® screw closures PP, ND10 with hole, septum silicone white/PTFE red, 10
What is this article?
neochrom® screw closures PP, ND10 with hole, septum silicone white/PTFE red, 10 is the article on this page. Luminix Health distributes neolab 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.
