Description
BOLA standard ground joint stirrer seal in SAFE LAB design guides a stirrer shaft through an NS 29/32 cone joint while maintaining a secure, adjustable seal. Built for a shaft diameter of 10 mm, the unit uses polytetrafluoroethylene (PTFE) construction for broad chemical resistance in stirred laboratory glassware. An adjustable special gasket allows the seal to be fine-tuned around the rotating shaft, supporting stable stirring with reduced leakage risk at the joint. The integrated Combi-nut (Safe-Lab) simplifies securing and releasing the ground cone, making assembly and dismantling faster during setup changes or cleaning. This single-piece accessory has a net weight of 0,135 kg and is intended for reaction flasks and apparatus that rely on standard NS 29/32 connections. From manufacturer Bohlender, the seal addresses everyday needs in synthesis, mixing and process development where PTFE contact surfaces and a practical locking nut improve handling. It belongs to laboratory stirrer-seal components used wherever a PTFE NS 29/32 guide for a 10 mm shaft is required in SAFE LAB configuration.
This article is part of Lids & seals, in Stoppers, caps & closures.

Questions about BOLA Stirrer Bearings, NS 29/32 Ø 10 mm PTFE, with SAFE LAB-system
What is this article?
BOLA Stirrer Bearings, NS 29/32 Ø 10 mm PTFE, with SAFE LAB-system 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.
