Description
neochrom® screw caps ND8 closed, rubber red-orange/TEF transparent, are black polypropylene screw closures with an 8-425 thread, supplied closed and equipped with a natural rubber red-orange / transparent TEF septum. Septum thickness is 1,3 mm, providing a dependable seal for ND8 vials in gas chromatography and HPLC sample introduction. The assembly withstands temperatures from −40 °C to +120 °C and is well suited to multiple injections thanks to favourable resealing properties of the rubber/TEF laminate. Delivered in packs of 100 pieces, these closed ND8 caps from manufacturer neolab - Labor represent a standard closure choice for GC and HPLC laboratories. The black PP shell shields the septum in storage and transport, while the transparent TEF layer forms the sample-facing surface. Use them wherever a closed ND8 screw cap with natural rubber/TEF septum is required for routine chromatographic vial sealing and repeated needle access under typical laboratory temperature conditions.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about neochrom® Schraubkappen ND8 geschl., Kautschuk rot-or./TEF transp., 100 St./Pack
What is this article?
neochrom® Schraubkappen ND8 geschl., Kautschuk rot-or./TEF transp., 100 St./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 Matériel de laboratoire.
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.
