Description
Pouring ring, red for GL 45, PP is a laboratory accessory designed for controlled dispensing from GL 45 threaded bottles and containers. Manufactured from polypropylene (PP), the ring provides a durable, chemically resistant interface that supports clean pouring and helps reduce drips during routine liquid handling. It is specified for the GL 45 thread standard widely used on laboratory reagent bottles, making it a practical fit for standard glass and plastic bottle systems. The red colour coding supports quick visual identification on the bench and in storage areas where multiple solvents or media are in use. According to the manufacturer data, the pouring ring is resistant up to 140 °C steam, supporting autoclave-related thermal exposure within the stated limit. Supplied as a single piece from manufacturer lab-o-plastix, this component is intended for laboratories that need a simple, colour-coded PP pouring aid matched to GL 45 closures. It suits general laboratory workflows involving aqueous and many common laboratory liquids where polypropylene compatibility and thermal steam resistance are required for bottle accessories.

Questions about Pouring ring, red for GL 45, PP
What is this article?
Pouring ring, red for GL 45, 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.
