Description
Screw cap, PP, for bottles GL 40 is a laboratory screw closure designed for bottles with a GL 40 neck thread. Manufactured from polypropylene (PP), it provides a straightforward mechanical seal for laboratory bottles used in sample storage, media preparation and general bench applications. The GL 40 thread is a recognised laboratory bottle finish, allowing this cap to serve as a convenient spare or replacement part wherever matching GL 40 bottles are employed. Each pack contains 12 pieces, enabling efficient stocking for research, teaching and quality-control laboratories that rely on interchangeable screw closures. These screw caps from manufacturer Vitlab are intended for everyday use with corresponding GL 40 bottles and fit standard laboratory workflows that require a simple PP closure without additional specialised components. Polypropylene construction offers a lightweight option suitable for routine laboratory handling of aqueous solutions and many common reagents within the normal chemical compatibility of PP. With origin in Germany, the product supports reliable sealing of GL 40 bottle systems across analytical, preparative and educational laboratory environments.

Questions about Screw-cap, PP, GL 40
What is this article?
Screw-cap, PP, GL 40 is the article on this page. Luminix Health distributes Vitlab 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.
