Description
BOLA Replacement Stirring Closure Screw Caps, GL 25 Ø 8 mm are dedicated screw caps for stirring closures that apply metered pressure to the O-ring of the special seal, thereby establishing the correct seal against the stirring shaft. They are specified for a shaft diameter of 8 mm and a cap thread of GL 25, matching the corresponding BOLA stirring-closure geometry. By controlling compression on the special-seal O-ring, the screw cap supports stable shaft sealing during stirring operations in laboratory glassware and apparatus. These replacement caps are supplied in a pack of 3 pc(s) with a net weight of 0,01 kg, making them suitable for maintenance kits and spare-part stocks for stirring systems. Positioned within the Rührverschlüsse category, they form the adjustable outer element that works with PTFE/FKM special seals and guide sleeves. From manufacturer Bohlender, the BOLA replacement screw caps allow straightforward exchange when wear or service intervals require new caps without replacing the entire stirring closure assembly. Correct pairing of GL 25 thread and 8 mm shaft diameter is essential for proper fit and sealing function.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA Replacement Screw Caps, GL 25 Ø 8 mm
What is this article?
BOLA Replacement Screw Caps, GL 25 Ø 8 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.
