Pouring ring, purple for GL 32, PP

Pouring ring, purple for GL 32, PP is a polypropylene accessory for laboratory bottles that use the GL 32 thread standard. The ring sits at the bottle neck to support cleaner, more controlled pouring of aqueous and other laboratory liquids and is finished in purple for clear visual coding among multiple vessels. Polypropylene (PP) construction provides the mechanical stability expected of routine lab plastics, while the stated resistance up to 140 °C under steam conditions allows the part to tolerate elevated-temperature steam exposure in typical laboratory practice.

Supplied as a single piece, this GL 32 pouring ring is intended for reagent bottles, media bottles and similar containers where drip control and colour differentiation matter in daily workflows. Purple coding helps staff link vessels to content type, process step or internal labelling schemes without relying solely on written labels. The geometry matches GL 32 necks commonly found on laboratory glass and plastic bottles, so the ring integrates directly into existing bottle systems. This pouring ring from manufacturer lab-o-plastix is a practical consumable-style component for analytical, teaching and research laboratories that standardise on GL 32 closures and wish to expand or replace colour-coded pouring aids.
