BOLA HT screw closure caps for GL 45 threads are black laboratory screw caps supplied without a bore and fitted with an internal stretched PTFE membrane gasket. The knurled PPS body provides a secure grip, while the chemically highly resistant and elastic PTFE seal ensures that, once screwed on, the medium contacts only PTFE by design. This construction supports demanding chemical handling and offers high mechanical and thermal load capacity up to a maximum of +250 °C. Intended for GL 45 bottle and vessel threads, the caps suit routine sealing tasks in analytical, preparative and general laboratory workflows where inert wetted surfaces matter. Each unit has a net weight of 0,03025 kg and is made for reliable closure performance under elevated temperature conditions. These BOLA components from manufacturer Bohlender combine a robust PPS outer structure with an inner PTFE membrane for durable, chemically resilient sealing. Pack size is 5 pc(s), practical for stocking standard GL 45 closures across lab benches and storage areas.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA HT Screw Caps, GL 45 without bore, black, with expanded PTFE gasket, max. t
What is this article?
BOLA HT Screw Caps, GL 45 without bore, black, with expanded PTFE gasket, max. t is the article on this page. Luminix Health distributes Bohlender for laboratory use. It sits in Schroefdoppen & sluitingen, inside Stoppen, doppen & sluitingen, in Labmateriaal.
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.
