Description
Screw closure for narrow-neck bottle 1000 ml is a laboratory screw cap with GL 28 thread, intended for matching Enghals (narrow-neck) bottles of 1000 ml capacity. Produced from PE-LD in a natural colour, it delivers a practical seal for routine laboratory storage, handling and transport of liquids and reagents in compatible larger-volume containers. The GL 28 thread is specified for secure engagement with the corresponding narrow-neck bottle finish, supporting sample handling, media storage and general bottle closure work at the one-litre scale. This PE-LD screw closure from manufacturer Witeg is supplied as a single piece and is appropriate for laboratories that need replacement caps or additional closures for PE-LD narrow-neck bottle systems. Natural-coloured low-density polyethylene construction keeps the cap lightweight and suitable for general lab use where PE-LD is the preferred material. Use it to reseal 1000 ml narrow-neck bottles after dispensing, sampling or preparation steps, helping maintain clear bottle organisation on the bench and in storage. The design emphasises simple screw-on function for standard laboratory workflows specifying GL 28 closures on 1000 ml narrow-neck bottles.

Questions about Closure narrow neck bottle 1000ml
What is this article?
Closure narrow neck bottle 1000ml is the article on this page. Luminix Health distributes Witeg 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.
