Description
Screw closure for narrow-neck bottle 100 ml is a PE-LD laboratory cap intended for sealing matching Enghals bottles with a GL 18 thread. Manufactured from low-density polyethylene in a natural colour, this screw closure delivers a lightweight, practical seal for 100 ml narrow-neck bottles used in chemical handling, sample storage and general laboratory work. The GL 18 thread provides secure engagement with compatible narrow-neck containers, supporting controlled use and helping to limit spills or evaporation during bench procedures, short-term storage or internal transport. Supplied as a single piece from manufacturer Witeg, the natural PE-LD closure fits everyday laboratory bottle systems based on flexible plastic. It pairs with PE-LD narrow-neck bottles in research, teaching and industrial quality-control environments for aqueous media and many routine reagents. Straightforward screw-on operation allows rapid opening and closing while maintaining a reliable fit on standard GL 18 narrow-neck laboratory bottles of 100 ml nominal volume.

Questions about Closure narrow neck bottle 100ml
What is this article?
Closure narrow neck bottle 100ml 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.
