Description
Stopper, PP, for tubes Ø 25/26 mm is a polypropylene laboratory stopper intended for tubes with 25/26 mm outer diameter. Made from PP, it serves as a practical plug for temporary sealing during sample holding, transfer between benches, or short-term storage in volumetric and general labware applications. The 25/26 mm sizing supports a secure match to corresponding larger tubes, helping reduce splash and evaporation during routine handling. Supplied in packs of 20 pc(s), the stoppers suit laboratories that need to equip several stations or keep shared drawers restocked. These PP stoppers from manufacturer Nalgene fit everyday vessel-closure tasks where a lightweight plastic option is preferred. Pack weight is 0,053 kg, making the unit easy to store and issue. They support research, teaching, and quality-control settings standardised on 25/26 mm tube formats and looking for consistent, straightforward closures without additional hardware complexity.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Stopper, PP, für Röhrchen Ø 25/26 mm, 20 unit(s)
What is this article?
Stopper, PP, für Röhrchen Ø 25/26 mm, 20 unit(s) is the article on this page. Luminix Health distributes Nalgene for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
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.
