Description
Pouring ring premium closure GL 45 is a laboratory bottle accessory that improves controlled pouring and sealing on GL 45 thread necks. The ring has a height of 4 mm and is manufactured from TpCH260, a high-performance fluoropolymer material similar to PFA, chosen for chemical resistance and thermal stability in demanding lab environments. A PTFE-coated silicone gasket provides a reliable seal against the bottle rim, helping reduce drips and improve handling when dispensing reagents, media or solvents. Packaged as 5 pieces, the component fits standard GL 45 laboratory bottles used in chemistry, life-science and quality-control settings. The premium closure design supports clean, repeatable pouring while protecting contents from contamination during open handling. This pouring ring from manufacturer Hirschmann is intended for routine bottle workflows where chemical inertness and a secure seal matter. Suitable for use with compatible glass or plastic GL 45 vessels in research, production support and analytical laboratories that require durable, fluoropolymer-based pouring accessories.

Questions about POURING RING, GL45, PREMIUM CAP
What is this article?
POURING RING, GL45, PREMIUM CAP is the article on this page. Luminix Health distributes Hirschmann 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.
