Description
BOLA Standard Ground Joint Stirrer Seals NS 29/32 for Ø 10 mm stirrer shafts are PTFE laboratory components for closing and sealing stirrer passages in ground-joint glassware. The ground joint core is produced from polytetrafluoroethylene and features raised sealing rings that reduce the contact area inside the joint socket, making the core easier to loosen and helping to limit glass breakage. A specialised PTFE seal combined with an FKM O-ring ensures correct sealing against the stirrer shaft when the GL screw cap of PPS applies controlled pressure. Dimensional data include a European-standard NS 29/32 core, use with 10 mm diameter stirrer shafts, an overall length of approximately 72 mm and a GL 25 cap thread. Available as one piece with a net weight of 0,1 kg, this Bohlender fitting supports laboratory stirring duties that demand chemical resistance and a secure shaft interface. The PTFE construction and GL-capped design provide a practical seal for standard NS joints on the laboratory bench.

Questions about BOLA Stirrer Bearings, NS 29/32 Ø 10 mm GL 25 PTFE, PTFE/FKM gasket
What is this article?
BOLA Stirrer Bearings, NS 29/32 Ø 10 mm GL 25 PTFE, PTFE/FKM gasket is the article on this page. Luminix Health distributes Bohlender 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.
