Description
Replacement PTFE ring NS 24/29 is a precision spare gasket for laboratory ground-joint apparatus. Produced from chemically inert polytetrafluoroethylene (PTFE), it acts as a replacement seal for FCH-V cores sized NS 24/29. The PTFE construction delivers excellent resistance to a wide range of chemicals and good thermal stability, enabling dependable sealing in distillation, synthesis and vacuum applications. Supplied as a single piece with a net weight of 0,001 kg, the ring is designed for straightforward exchange when the original seal becomes worn, deformed or contaminated. Restoring the joint with this spare helps maintain leak-tight connections without changing the geometry of the glassware. The item belongs to the category of ground-joint sleeves, collar seals and related laboratory fittings and is manufactured by Witeg in Germany. Its small footprint and robust material properties make it a practical consumable for laboratories that need consistent joint performance across frequent assembly, cleaning and reassembly cycles in both analytical and preparative work.

Questions about Spare seals VITON ST 24/29
What is this article?
Spare seals VITON ST 24/29 is the article on this page. Luminix Health distributes Witeg 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.
