Description
Rotilabo® ridged sleeves in PTFE are conical ground-joint seals sized NS 14/23 for leak-resistant connections in laboratory glassware assemblies. The ridged PTFE design improves seating on standard conical joints and helps maintain a reliable seal during distillation, extraction and general apparatus work without grease in many setups. Supplied in a pack of 10 units, the sleeves suit routine joint maintenance and multi-apparatus configurations. Offered under the Rotilabo® selection (ROTH SELECTION), they are intended for NS 14/23 conical ground joints commonly found on flasks, condensers and adapters. PTFE provides broad chemical resistance and thermal stability appropriate for organic and aqueous laboratory chemistry. These ridged sleeves support quick assembly and disassembly while protecting ground surfaces from seizing. They are a practical consumable for teaching labs and research groups that rely on standardised European ground-joint glassware and need consistent sealing performance at the NS 14/23 interface.
This article is part of Distillation heads, adapters & columns, in Distillation & extraction glassware.

Questions about Rotilabo®-ridged sleeves, PTFE, conical ground joint NS 14/23, 10 unit(s)
What is this article?
Rotilabo®-ridged sleeves, PTFE, conical ground joint NS 14/23, 10 unit(s) is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Grease, boiling stones & sealants, inside Tools & accessories, in Labware.
Grease seals a ground joint. Boiling stones give a liquid a place to start boiling so it does not bump. A sealant does the same job as grease when grease would contaminate the product. They are small, and they decide whether a joint weeps.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
