Description
Pouring rings in PTFE are slim laboratory accessories that improve controlled pouring from bottles and vessels fitted with compatible neck systems. Each ring has a height of 6,85 mm and is manufactured from polytetrafluoroethylene, a material widely used in labware for its chemical inertness and clean handling characteristics. The rings support drip-reduced transfer of liquids during media preparation, reagent dispensing and routine sample work, helping keep bottle necks and work surfaces cleaner. Offered as a pack of 5 pc(s) with a combined weight of only 0,010 kg, they are easy to stock as spares alongside seals, hose connectors and other bottle accessories. These pouring rings from manufacturer DWK Life Sciences complement laboratory containers, bottles and canisters where a PTFE pouring aid is preferred. Their compact profile fits neatly into existing glassware and plasticware setups used for storage and transfer. Suitable for general laboratory use wherever PTFE pouring rings are specified for bottle necks and related sealing accessories.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Pouring rings, PTFE, H 6.85 mm, 5 unit(s)
What is this article?
Pouring rings, PTFE, H 6.85 mm, 5 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences 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.
