Description
Screw caps with hole in PPS provide threaded laboratory closures that combine a secure seal with an open centre for tubing, sensors, or other feed-throughs. This version is specified for GL 45 threads and incorporates a hole diameter of 34 mm, matching common laboratory bottle and vessel formats that use the GL 45 standard. The polyphenylene sulfide construction is rated for service from −50 to +250 °C, covering cold storage, room-temperature work, and higher-temperature applications within that range. Each pack contains 10 pc(s), supporting regular replacement and multi-station setups in research, quality control, and process laboratories. These items sit within the seals, hose connectors and accessories category for containers, bottles, tins and canisters and come from manufacturer Bohlender. Pack weight is 0,300 kg. The combination of GL 45 threading, a 34 mm aperture, and PPS material makes the caps a clear choice when vessels must remain closed yet still accommodate lines or probes through the lid.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps with hole, PPS, GL 45, Ø hole 34 mm, -50 to +250 °C, 10 unit(s)
What is this article?
Screw caps with hole, PPS, GL 45, Ø hole 34 mm, -50 to +250 °C, 10 unit(s) 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.
