Beschrijving
BOLA screw caps HT, GL 25 without bore, black, with stretched PTFE are laboratory screw closures for GL 25 threaded necks. The black knurled PPS cap body carries an internal, chemically highly resistant and elastic PTFE membrane seal. When fitted, the medium comes into contact only with PTFE by design, which supports chemically demanding laboratory media. Mechanically and thermally highly loadable up to a maximum of +250 °C, these HT caps suit elevated-temperature use. Stretched PTFE forms the sealing membrane, and the without-bore layout provides a solid, continuous closure without ports or openings. Pack size is 10 pc(s); net weight is 0,01115 kg. Offered in the BOLA HT range from manufacturer Bohlender, the caps address sealing of glass bottles and vessels with GL 25 threads where inert wetted surfaces and secure manual grip are required. They fit chemical, analytical and process workflows that need a robust PPS/PTFE screw closure without bore for storage or intermediate process steps.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA HT Screw Caps, GL 25 without bore, black, with expanded PTFE gasket, max. t
What is this article?
BOLA HT Screw Caps, GL 25 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 Screw caps & closures, inside Stoppers, caps & closures, 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.
