Description
Rotilabo® PTFE clamps for conical ground joints NS 19/26 are laboratory joint clips for securing standard conical ground glass joints in everyday glassware assemblies. Each clamp is made of PTFE-encased steel, pairing a steel core for mechanical hold with a PTFE outer layer that supports chemical resistance and clean contact against glass. The NS 19/26 format matches common conical ground joints used in synthesis setups, distillation trains, condensers, adapters, and connecting pieces. Supplied as 1 pc and weighing 0,015 kg, the clamp is a compact accessory for stoppers-and-clamps workflows on the bench. PTFE encasement helps limit sticking at the joint interface while the steel structure provides the retention force needed to keep conical ground joints aligned during handling and operation. These Rotilabo® clamps from manufacturer ROTH SELECTION suit routine laboratory glassware work where reliable joint retention is required without adding bulk. They integrate with standard labware categories for vessels, joints, and consumables and are sized specifically for NS 19/26 conical ground joints. Use them wherever a durable PTFE-encased steel joint clip is specified for conical ground joint assemblies in chemical and general laboratory practice.

Questions about Rotilabo®-PTFE clamps f. con. gr. joints, NS 19/26, made of PTFE-encased steel
What is this article?
Rotilabo®-PTFE clamps f. con. gr. joints, NS 19/26, 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.
