Description
Sealing ring for unground spherical joints (silicone + FEP), size S 13, provides the sealing function for DURAN® spherical joints that lack ground surfaces. Unground spherical joints seal exclusively by means of the sealing ring rather than a ground-glass interface. The ring is made of silicone with an FEP jacket, combining elasticity with high chemical resistance for laboratory work that places stringent demands on seal materials. FEP-coated silicone rings are selected whenever elevated chemical durability is required. This sealing ring from manufacturer Duran/DWK Life Sciences is intended for sealing unground spherical joints in laboratory glassware assemblies. Supplied as a single piece with a net weight of 0,001 kg, it integrates readily into existing apparatus. The silicone-plus-FEP construction supports reliable, chemically robust sealing across a broad range of reagents and process conditions encountered in research and preparative laboratories, ensuring leak-tight performance where standard elastomers would be unsuitable.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about Sealing ring , for polished sperical joints (silicone + FEP)
What is this article?
Sealing ring , for polished sperical joints (silicone + FEP) is the article on this page. Luminix Health distributes DWK Life Sciences 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.
