Description
BOLA Replacement Stirrer Sealing Screw Caps EX, GL 25 for Ø 8 mm shafts, are screw caps manufactured from PPS-EX with a GL thread. They are intended for sealing the stirrer shaft in BOLA stirrer closures EX: the cap presses onto the O-ring of the special seal and thereby supplies the compression needed for reliable shaft sealing.
This article is part of Screw caps & closures, in Stoppers, caps & closures.
Each cap is threaded GL 25 and matched to stirrer shafts of 8 mm diameter. When tightened on the corresponding EX stirrer closure, the PPS-EX screw cap applies controlled pressure to the special seal so that the shaft remains sealed during stirring. These components from manufacturer Bohlender function as genuine replacement caps for the original EX stirrer sealing screw caps of this size and thread.
Supplied as a pack of 3 pieces with a net weight of 0,0112 kg, the set is convenient for spare-parts stocking beside BOLA EX stirring equipment. Proper performance requires pairing with the matching special seal and an 8 mm shaft within a BOLA Rührverschluss EX that uses a GL 25 centre neck. Used in this configuration, the PPS-EX caps restore the clamping and sealing action of the stirrer closure without changing the rest of the assembly, supporting continued laboratory operation of EX-rated BOLA stirrer systems.

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