Description
BOLA replacement stirrer sealing screw caps, GL 25 for shaft diameter 10 mm, are specialised laboratory spare parts for sealed stirring assemblies. They apply controlled pressure to the O-ring of a special seal so that the interface with the stirrer shaft remains correctly closed during mixing. Intended as Ersatz components for Rührverschlüsse, these screw caps restore sealing performance when original caps wear or need renewal, without replacing the full closure. The GL 25 cap thread matches common laboratory glassware and reactor connections used with overhead stirrers, while the 10 mm shaft opening suits correspondingly sized stirring shafts. Supplied in a pack of 3 pc(s) with a net weight of 0,01 kg, the set supports routine maintenance stock in chemical, pharmaceutical and research laboratories. These BOLA parts from manufacturer Bohlender help limit leakage around the shaft, support process integrity and keep sealed vessels workable under typical laboratory stirring conditions. Use them wherever GL 25 stirrer closures require reliable, replaceable screw-cap sealing elements for ongoing experimental work.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA Replacement Screw Caps, GL 25 Ø 10 mm
What is this article?
BOLA Replacement Screw Caps, GL 25 Ø 10 mm is the article on this page. Luminix Health distributes Bohlender 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.
