Description
Pouring ring, yellow for GL 32, PP is a polypropylene pouring accessory for laboratory bottles that employ the GL 32 thread. The ring fits the bottle neck to guide liquid flow during dispensing and is coloured yellow to enable fast visual separation of vessels on the bench or in storage. Polypropylene (PP) delivers the robustness required for repeated laboratory use, and the part is resistant up to 140 °C under steam conditions, supporting workflows that involve steam exposure at elevated temperature.
This article is part of Screw caps & closures, in Stoppers, caps & closures.
Packaged as a single piece, this yellow GL 32 pouring ring suits reagent bottles, media bottles and comparable containers where controlled pouring and colour coding improve handling clarity. Yellow identification helps teams map bottles to content categories, process stages or local labelling conventions at a glance. Thread geometry aligns with the widely used GL 32 laboratory bottle standard, allowing direct use on matching necks. Available from manufacturer lab-o-plastix, the ring is a simple add-on or spare for facilities that rely on GL 32 systems and prefer colour-coded pouring components for routine analytical, teaching and research applications.

Questions about Pouring ring, yellow for GL 32, PP
What is this article?
Pouring ring, yellow for GL 32, PP is the article on this page. Luminix Health distributes lab-o-plastix 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.
