Description
Sealing ring/Rotulex 41/25 is a laboratory sealing accessory for Rotulex spherical joint systems used on glassware. The ring is dimensioned for the 41/25 size and acts as a purpose-made sealing component alongside standard laboratory stoppers and related seals. Delivered as a single piece, it is appropriate for building or maintaining glass assemblies that employ Rotulex joints to connect reaction vessels, adapters and other apparatus. This sealing ring from manufacturer LAT forms part of the assortment covering norm stoppers, cork, rubber, silicone and cellulose stoppers, providing a practical replacement item for routine laboratory work. Facilities engaged in research, education or analytical chemistry that specify Rotulex 41/25 joints can incorporate the ring when preparing apparatus or exchanging worn seals. Clear identification as Rotulex 41/25 helps ensure the correct match to existing joint sizes. The one-piece pack format facilitates orderly stock management and individual replacement without excess material on the shelf.

Questions about Sealing ring/Rotulex 41/25
What is this article?
Sealing ring/Rotulex 41/25 is the article on this page. Luminix Health distributes LAT for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Matériel de laboratoire.
Lids and seals are the covers of dishes, jars and tanks: a snap lid, a sealing film, a gasket. The seal is doing the work. A lid that only rests on the rim does not contain a volatile liquid.
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.
