Description
Screw cap with PP cap and ring (blue) GL 80 is a laboratory closure assembly that pairs a polypropylene screw cap with a blue ring for wide-neck GL 80 bottles, referenced as 91800002271. Supplied in packs of 10 pieces, it provides ready replacements for large laboratory bottles used in media preparation, storage and general wet-lab work. The polypropylene cap and ring are matched to the GL 80 thread so that bottles can be closed consistently without altering existing glassware. Blue colouring of the ring aids quick visual sorting among mixed bottle sizes on shelves and benches. Offered by manufacturer Dinkelberg, this screw-cap set is aimed at laboratories that standardise on GL 80 necks for bulk reagents or culture media. Origin is the Czech Republic. The ten-piece unit quantity supports stock rotation in research, teaching and industrial laboratory environments where spare wide-neck closures are kept on hand. Fit the complete blue PP cap and ring whenever a GL 80 polypropylene screw closure is specified for laboratory bottles, maintaining a uniform sealing approach across the glassware fleet.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw Cap, with PP-Cap and Ring (blue) GL 80 91800002271, 10/PK
What is this article?
Screw Cap, with PP-Cap and Ring (blue) GL 80 91800002271, 10/PK is the article on this page. Luminix Health distributes Dinkelberg 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.
