Description
BOLA replacement stirrer sealing screw caps, GL 25 for shaft diameter 16,5 mm, provide dedicated spare sealing elements for laboratory stirring closures. By exerting dosed pressure on the O-ring of the special seal, each cap establishes the correct seal against the stirrer shaft and helps maintain a closed system during agitation. They are suited to GL 25 threaded stirrer assemblies where the shaft measures 16,5 mm and original screw caps must be renewed. As part of the BOLA range from manufacturer Bohlender, these components support sealed mixing in glassware, reactors and related laboratory setups used in chemistry and life-science work. The pack contains 2 pc(s) and has a net weight of 0,0096 kg, making it practical for bench-side maintenance inventories. Laboratories operating overhead stirrers with GL 25 connections can use these replacement screw caps to restore shaft sealing without exchanging the entire closure. Consistent O-ring contact aids leakage control and process reliability whenever sealed stirring is required for reproducible experimental conditions.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA Replacement Screw Caps, GL 25 Ø 16,5 mm
What is this article?
BOLA Replacement Screw Caps, GL 25 Ø 16,5 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.
