Description
BOLA screw caps HT, GL 32 without bore, black, with stretched PTFE are laboratory screw closures for GL 32 threaded necks. Each black cap combines a grippy knurled PPS body with an internal, chemically highly resistant and elastic PTFE membrane seal. Screwed on, the medium contacts only PTFE by design, supporting aggressive or sensitive chemical contents. The HT design is mechanically robust and thermally loadable up to a maximum of +250 °C for demanding thermal conditions. Stretched PTFE supplies the sealing membrane, while the without-bore construction yields a continuous solid closure without ports. Pack size is 5 pc(s); net weight is 0,01942 kg. These BOLA HT screw caps from manufacturer Bohlender serve glassware and vessels with GL 32 threads where inert wetted surfaces, secure grip and high thermal load capacity are needed. They suit chemical, analytical and process laboratory sealing tasks that require a PPS/PTFE screw closure without bore for reliable containment during storage or process handling.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about BOLA HT Screw Caps, GL 32 without bore, black, with expanded PTFE gasket, max. t
What is this article?
BOLA HT Screw Caps, GL 32 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 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.
