Description
neochrom® UltraBond closures ND9 black unite cap and septum into one inseparable UltraBond™ assembly so the septum cannot be pushed into the vial by a blunt needle. The bonded silicone white/PTFE red septum is specified for single-injection use and is temperature resistant from −60 °C to +200 °C. Septum thickness is 1,3 mm with a hardness of 45° Shore A, giving a defined sealing stack for ND9 short-thread chromatography vials. Each unit pack contains 100 pieces for continuous laboratory supply. These UltraBond™ closures from manufacturer neolab - Labor address a common failure mode of loose septa during automated or manual piercing, keeping the liner fixed in the black cap throughout handling and injection. The silicone/PTFE combination supports first-puncture performance typical of disposable analytical workflows in HPLC and GC sample introduction. Laboratories that need reliable ND9 sealing without septum dislodgement can specify this bonded black configuration as a dedicated single-injection consumable for routine vial work.

Questions about neochrom® UltraBond closures ND9 black, septum silicone white/PTFE red, 100 S
What is this article?
neochrom® UltraBond closures ND9 black, septum silicone white/PTFE red, 100 S 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.
