Description
BOLA standard ground joint stirrer seals EX provide a sealed passage for a stirrer shaft through a ground joint while supporting controlled discharge of static charge. The ground joint core is made of PTFE-EX and carries raised sealing rings that seal inside the ground joint socket. A special PTFE-EX seal with an FKM O-ring works together with the metered pressure of the GL screw cap in PPS-EX to seal against the stirrer shaft. A bore with internal thread M5 on the knurl allows static charges to be discharged. Key dimensions are core NS 29/32, shaft diameter 10 mm, overall length approximately 72 mm, and cap thread GL 25. This BOLA seal from manufacturer Bohlender is supplied as 1 pc with a net weight of 0,0869 kg. The combination of PTFE-EX body and seal, FKM O-ring and PPS-EX screw cap is intended for laboratory stirrer setups that need a ground-joint interface, shaft sealing and a defined path for electrostatic discharge at the knurled section.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about BOLA Stirrer Bearings EX, NS 29/32 Ø 10 mm GL 25 Body made of PTFE-EX, screw cap
What is this article?
BOLA Stirrer Bearings EX, NS 29/32 Ø 10 mm GL 25 Body made of PTFE-EX, screw cap 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.
