Description
Rotilabo®-PTFE stopper NS 14/23 is a laboratory stopper for standard taper joints used throughout glass apparatus. Fabricated from PTFE, it provides an inert sealing interface for flasks, condensers, adapters and similar vessels in day-to-day laboratory work. The NS 14/23 joint size is a widely adopted intermediate taper, ensuring broad compatibility with common European ground-glassware systems. The item is packed as 1 pc and has a weight of 0,014 kg, convenient for stocking multiple sizes side by side. As part of the Rotilabo® assortment from manufacturer ROTH SELECTION, it belongs with stoppers and clamps for laboratory glass, vessels and consumables. PTFE supports use where chemical resistance and easy cleaning matter, and the solid stopper body seats firmly in matching NS 14/23 sockets for temporary closure or process steps that do not require greased joints. Applications span synthesis work-up, sample preparation, teaching laboratories and QC benches that rely on interchangeable NS connections. This Rotilabo®-PTFE stopper helps keep assemblies sealed and organised when NS 14/23 ports must be closed between operations or during storage of intermediate solutions.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-PTFE stopper, NS 14/23, 1 unit(s)
What is this article?
Rotilabo®-PTFE stopper, NS 14/23, 1 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
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.
