Description
neochrom® PE snap ring caps ND11 white with silicone white/PTFE blue cross-slit septum are laboratory closure components for analytical sample vials. These white polyethylene snap ring caps incorporate a 6 mm centre hole and are intended for single-injection use. The pre-assembled septum pairs a white silicone layer with a blue PTFE face; the cross-slit geometry eases needle penetration in autosampler workflows while supporting a practical seal at the vial neck. Cap thickness is 1,0 mm and septum thickness is 1,3 mm. Temperature resistance from −60 °C to +200 °C covers typical GC and HPLC sample-handling ranges. Offered in packs of 100 pieces from manufacturer neolab - Labor, the neochrom® ND11 snap-ring format fits common short-neck vial systems used in routine chromatography and quality-control laboratories. The PE outer shell provides a lightweight mechanical closure, while the silicone/PTFE septum balances resealing behaviour with chemical inertness at the sample interface. These caps suit labs standardising on ND11 snap-ring vials for high-throughput injection sequences where consistent septum performance and straightforward snap-on application are required day to day.

Questions about neochrom® PE-Schnappringkappen ND11 weiß, Septum Silikon weiß/PTFE blau, kreuzge
What is this article?
neochrom® PE-Schnappringkappen ND11 weiß, Septum Silikon weiß/PTFE blau, 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.
