Description
Sealing ring/Rotulex 19/9 is a laboratory sealing component sized for Rotulex joints of designation 19/9. It serves as a dedicated ring element within standard glassware and stopper assemblies used across chemical, analytical and medical laboratory work. The item is supplied as a single piece and integrates into setups that rely on reliable joint interfaces for closed systems. Categories associated with this product include norm stoppers, cork stoppers, rubber stoppers, silicone stoppers and cellulose stoppers, underscoring its role among common sealing accessories. Manufactured by LAT, the sealing ring supports secure connections when pairing corresponding Rotulex joint halves in apparatus. Laboratory personnel employ such rings to maintain alignment and contact at spherical or ground interfaces during routine handling of liquids or gases. The 19/9 sizing matches established joint dimensions found in many glass assemblies, allowing straightforward replacement or expansion of existing equipment collections. Packaged individually, the component offers convenient stocking for workshops and teaching laboratories that maintain modular glassware inventories. Its straightforward design focuses on compatibility within the Rotulex system without requiring additional adapters for standard configurations.

Questions about Sealing ring/Rotulex 19/9
What is this article?
Sealing ring/Rotulex 19/9 is the article on this page. Luminix Health distributes LAT for laboratory use. It sits in Lids & seals, inside Stoppers, caps & closures, in Labware.
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.
