Description
neochrom® screw cap ND15 closed is a black polypropylene closure fitted with a white silicone/red PTFE septum for reliable sealing of ND15 screw-thread vials in routine laboratory workflows. The bonded septum measures 1,3 mm in thickness and offers a hardness of 45° shore A, supporting clean single-injection sampling while limiting coring and analyte interaction. Temperature resistance from −60 °C to +200 °C covers chilled storage through elevated sample preparation and analysis conditions. Designed as a closed cap with integrated septum, it is intended for disposable injection use in chromatography and general analytical sample handling. Supplied in practical packs of 100 pieces, these neochrom® closures from manufacturer neolab - Labor give laboratories a consistent consumable for high-throughput vial work. The PP body provides mechanical stability on the thread, while the silicone/PTFE laminate balances resealability with chemical inertness toward many solvents and matrices. Ideal for standard ND15 formats where a closed, septum-equipped screw cap is required without additional hardware.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about neochrom® Schraubkappe ND15 geschl., PP, Silikon weiß/PTFE rot, 100 Stck./Pack
What is this article?
neochrom® Schraubkappe ND15 geschl., PP, Silikon weiß/PTFE rot, 100 Stck./Pack 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.
