Description
Rotilabo®-PTFE clamps for conical ground joints NS 45/40 are laboratory joint clips intended to secure standard conical ground glass connections. Constructed from PTFE-encased steel, they combine a robust steel core with a chemically resistant PTFE outer layer, so metal does not contact the glass joint surface. The NS 45/40 format matches widely used conical ground joint sizes found on flasks, condensers and reaction assemblies. Each unit is supplied as 1 pc and weighs 0,040 kg, offering a compact fastening aid for routine and specialised glassware setups. These Rotilabo® clamps from manufacturer ROTH SELECTION sit within the stoppers and clamps range and support stable joint retention during heating, stirring, distillation or vacuum work. PTFE encasement helps the clip withstand exposure to many laboratory chemicals while remaining easy to fit and remove. Suitable for laboratories that rely on conical ground joints in everyday apparatus, the clamps provide a practical, durable means of keeping connections aligned and closed without additional hardware.

Questions about Rotilabo®-PTFE clamps f. con. gr. joints, NS 45/40, made of PTFE-encased steel
What is this article?
Rotilabo®-PTFE clamps f. con. gr. joints, NS 45/40, made of PTFE-encased steel is the article on this page. Luminix Health distributes Carl Roth 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.
