Description
Screw caps with hole, PPS are specialised laboratory closures for vessels with GL 25 screw threads, each fitted with a circular aperture of 15 mm. Polyphenylene sulphide construction delivers mechanical strength together with a service temperature range from −50 to +250 °C, supporting both low-temperature and heated laboratory applications. The open centre accommodates tubing, probes or other inserts while the threaded body maintains a secure connection on compatible bottles and containers. Packs contain 10 pc(s) at a total weight of 0,100 kg, convenient for everyday laboratory stocking. These screw caps with hole from manufacturer Bohlender fit within the range of seals, hose connectors and accessories used alongside laboratory glassware and vessels. Laboratories choose them when controlled access through a defined hole is needed for sampling, media transfer or instrument insertion without fully removing the closure. The 15 mm hole diameter and GL 25 geometry aid standardisation across setups. PPS helps retain dimensional stability under repeated thermal cycling within the stated limits, making the caps a practical option for research, analytical and quality-control workflows that rely on robust screw closures.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps with hole, PPS, GL 25, Ø hole 15 mm, -50 to +250 °C, 10 unit(s)
What is this article?
Screw caps with hole, PPS, GL 25, Ø hole 15 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.
