Description
Pouring rings for narrow-mouth bottles are high-form accessories sized for thread 32, enabling controlled dispensing from laboratory EH bottles. Fitted under a matching safety screw cap, the ring guides liquid flow along the bottle neck and helps reduce dripping and run-back onto the outer wall during transfer of reagents, media or process solutions. The high-form design supports clean pouring in chemical, pharmaceutical and life-science workflows where accurate, mess-free decanting improves bench hygiene and sample handling. Supplied as 10 pc(s) with a pack weight of 0,009 kg, the rings are convenient consumables for laboratories standardising on thread-32 narrow-mouth bottles. Compatible with corresponding safety screw cap closures from manufacturer DWK Life Sciences, they integrate into existing bottle systems used for storage and short-term holding of liquids. These pouring rings are intended for routine laboratory use wherever controlled pouring from narrow-mouth containers is required, supporting safer transfers between bottles, beakers and reaction vessels without altering the basic bottle geometry.
This article is part of Plastic bottles (narrow & wide mouth), in Bottles & containers.

Questions about Pouring rings for narrow-mouth bottles, for thread 32, high form, 10 unit(s)
What is this article?
Pouring rings for narrow-mouth bottles, for thread 32, high form, 10 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Plastic bottles (narrow & wide mouth), inside Bottles & containers, in Labware.
A plastic bottle is polyethylene, polypropylene or a fluoropolymer, narrow-mouth for pouring or wide-mouth for powders. It is the choice when the bottle must not shatter, and it is the wrong choice for solvents that swell the plastic.
A laboratory bottle is a closed container with a stated volume and a neck that takes a cap, a stopper or a dispenser. Borosilicate glass is the choice when the liquid is a solvent, or when the bottle will be heated or autoclaved. Polyethylene and polypropylene are the choice when the bottle must not shatter, or when hydrofluoric acid would attack glass. A narrow mouth pours. A wide mouth is for powders and for reaching the bottom. Laboratory ware of this kind is indexed under ISO laboratory glassware. Traceable volume sits with the BIPM and NIST Physical Measurement.
