Description
Pouring ring, green for GL 32, PP is a polypropylene laboratory accessory designed for neat, controlled pouring from bottles with a GL 32 neck thread. Positioned on the bottle rim beneath a compatible screw cap, the ring directs liquid flow and helps minimise drips when dispensing aqueous solutions, culture media, or common laboratory reagents. The green colour provides clear visual coding for bottle groups and supports efficient organisation on the bench or in storage. Constructed from polypropylene (PP), the pouring ring combines chemical robustness for routine laboratory use with resistance to steam up to 140 °C, allowing it to remain on bottles during standard steam sterilisation cycles. Supplied as one piece from manufacturer lab-o-plastix, this GL 32 pouring ring pairs with matching GL 32 closures and bottles in chemical, biological, and general analytical laboratories. It serves as a practical replacement component or as part of a colour-coded GL 32 bottle system, offering dependable handling performance while retaining compatibility with established laboratory bottle thread standards.

Questions about Pouring ring, green for GL 32, PP
What is this article?
Pouring ring, green 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.
