Description
PTFE seal for cones and sockets NS 10 provides a reliable, grease-free interface for standard ground-glass joints. Sized for NS 10/19, the seal prevents seizing of cone and socket pairs while establishing a gas- and liquid-tight connection between interchangeable glass components. A practical knurled grip allows effortless separation of stuck joints without tools or excessive force. The PTFE construction delivers vacuum-tight performance without sealing grease, reducing contamination risk and simplifying cleaning in synthesis, distillation and general laboratory assemblies. Suitable wherever Normschliff glassware must be joined cleanly and repeatedly, this ground-joint seal from manufacturer Rettberg supports routine and vacuum applications alike. Supplied as 1 pc, it is a compact accessory for maintaining leak-free, easily demountable apparatus in research and quality-control laboratories.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about PTFE-seal for cones and sockets NS 10
What is this article?
PTFE-seal for cones and sockets NS 10 is the article on this page. Luminix Health distributes Rettberg 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.
