Description
neoChoice screw cap GL 45 with pouring ring is a red polypropylene laboratory closure fitted with a lip seal and an integrated pouring ring for GL 45 bottle threads. These PP screw caps are steam-sterilisable up to 121 °C, allowing use in standard autoclave cycles common in research and quality-control laboratories. The pouring ring supports controlled dispensing of bottle contents while the lip seal helps achieve a reliable fit on matching GL 45 neck finishes. Supplied in a pack of 10 pieces, the red neoChoice caps from manufacturer neolab - Labor are intended for routine sealing of laboratory glass and plastic bottles during storage, transport and sample handling. Polypropylene construction provides the chemical resistance profile typically expected of this material for general laboratory applications. The standardised GL 45 thread ensures broad compatibility with common reagent, media and sample bottles. Colour coding in red aids visual organisation of bottle stocks, and the combination of autoclave compatibility, lip seal and pouring ring makes these closures practical for everyday laboratory workflows requiring secure yet convenient bottle closure.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about neoChoice closure cap GL 45, with pouring ring, PP, red, pack of 10 pieces
What is this article?
neoChoice closure cap GL 45, with pouring ring, PP, red, pack of 10 pieces is the article on this page. Luminix Health distributes neolab 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.
