Description
Pouring ring GL 32 blue PP is a laboratory bottle accessory that fits GL 32 screw threads and supports clean, controlled dispensing of liquids. Made from polypropylene (PP) in a distinctive blue colour, the ring is placed between the bottle neck and the closure to form a defined pouring lip, helping to reduce drips and improve handling during routine transfer of reagents and media. It is intended for use with matching GL 32 laboratory bottles in chemistry, biology and general analytical workflows where polypropylene offers suitable chemical resistance for everyday applications. Pack size is 10 pc(s), with each ring weighing only 0,001 kg net, so the accessory adds negligible mass to the bottle assembly. These pouring rings from manufacturer Witeg are compact, lightweight components that integrate easily into standard laboratory glassware and plastic bottle systems. The blue PP construction allows quick visual identification among other thread accessories, while the GL 32 format matches widely used media and reagent bottles. Suitable for everyday pouring tasks, the ring contributes to tidier bench work and more reliable liquid handling without altering the bottle’s primary sealing function.

Questions about Screw caps GL 32
What is this article?
Screw caps GL 32 is the article on this page. Luminix Health distributes Witeg 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.
