Description
neoChoice stirring closure GGM NS 29, KPG 10 is a precision ground-joint stirring seal for laboratory flasks fitted with an NS 29 neck. The closure incorporates an adjustable and exchangeable PTFE bearing sleeve that guides the stirrer shaft while maintaining a secure interface at the joint. A double seat of the bearing sleeve is ground into the NS joint, improving alignment and mechanical stability during prolonged stirring. This long-life design supports repeated use in synthesis, extraction and general process work where reliable shaft guidance and joint integrity are essential. The GGM-compatible format with KPG 10 geometry fits standard laboratory stirring arrangements and allows the PTFE sleeve to be readjusted or replaced as wear occurs, extending service life without discarding the entire closure. From manufacturer neolab - Labor, the unit is supplied as a single piece for straightforward installation on NS 29 glassware. It is well suited to teaching laboratories, preparative chemistry and routine R&D setups that require a durable, serviceable stirring closure rather than a disposable seal.

Questions about neoChoice Rührverschluss GGM NS 29, KPG 10
What is this article?
neoChoice Rührverschluss GGM NS 29, KPG 10 is the article on this page. Luminix Health distributes neolab for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Labware.
A screw cap has a thread and a liner. The thread has to match the bottle. The liner has to survive the liquid: a pulp liner fails in a solvent that a PTFE-faced liner ignores. The colour of the cap is not the specification.
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.
