Description
neochrom® PE snap ring caps ND11 blue with silicone white/PTFE blue cross-slit septum are laboratory closures for analytical sample vials. These blue polyethylene snap ring caps feature a 6 mm centre hole and are specified for single-injection applications. The integrated septum combines white silicone with a blue PTFE contact face; cross-slit cutting supports smooth needle entry during autosampler runs while helping maintain a reliable seal on the vial. Cap thickness is 1,0 mm and the septum measures 1,3 mm. The assembly is temperature-resistant from −60 °C to +200 °C, matching common GC and HPLC sample-preparation and injection conditions. Available in packs of 100 pieces from manufacturer neolab - Labor, the neochrom® ND11 format aligns with widely used snap-ring vial systems in routine analytical laboratories. Colour-coded blue PE shells aid visual differentiation on the bench or in trays, while the silicone/PTFE septum construction offers a practical balance of resealability and chemical resistance at the sample interface for standardised high-throughput injection workflows.

Questions about neochrom® PE snap ring caps ND11 blue, septum silicone white/PTFE blue, kreuzge
What is this article?
neochrom® PE snap ring caps ND11 blue, septum silicone white/PTFE blue, kreuzge 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.
