Description
Rotilabo®-PTFE stopper NS 24/29 is a laboratory stopper for larger standard taper joints on flasks and related glass apparatus. Made from PTFE, it supplies an inert sealing surface suitable for routine chemical work, sample containment and assembly of conical-joint equipment. The NS 24/29 size corresponds to a common larger joint, ensuring fit with many round-bottom flasks, filter flasks and multi-neck vessels found in research and teaching laboratories. Each stopper is offered as 1 pc with a weight of 0,042 kg, appropriate for dedicated glassware stations and shared consumable stocks. Belonging to the Rotilabo® line from manufacturer ROTH SELECTION, it is categorised among stoppers and clamps for laboratory glass, vessels and consumables. PTFE construction supports chemically demanding environments where clean, easily rinsed seals are preferred over greased glass stoppers. In practice the stopper closes NS 24/29 sockets during storage, transfer, work-up or idle periods between process steps. It suits organic synthesis, preparative chemistry, analytical sample handling and QC benches that standardise on interchangeable ground joints, providing a durable PTFE sealing option for medium-to-large laboratory glassware trains.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Rotilabo®-PTFE stopper, NS 24/29, 1 unit(s)
What is this article?
Rotilabo®-PTFE stopper, NS 24/29, 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.
