Description
Degassing closure in polypropylene (PP) is a specialised laboratory bottle cap for GL 45 threaded vessels where controlled gas exchange is needed alongside a secure seal. The red PP body is fitted with a PTFE insert, combining polypropylene durability with PTFE chemical resistance at the sealing interface. This configuration is intended for bottles holding media that may generate pressure or require venting during storage and handling in research and analytical laboratories. Supplied as 10 pieces per pack from manufacturer KAUTEX, the closures match standard GL 45 laboratory bottle necks used for reagents, buffers, and process solutions compatible with PP and PTFE. The distinctive red colour supports quick visual identification among other caps on the bench or in storage. Pack weight is 0,231 kg, making the set easy to manage within plastic-bottle and labware inventories. Typical use includes chemistry, life-science, and quality-control environments where degassing capability, GL 45 compatibility, and a PTFE-lined seal are required without compromising routine bottle handling.
This article belongs on Screw caps & closures, in Stoppers, caps & closures.

Questions about Degassing closure, PP, red, PTFE insert, GL 45, 10 unit(s)
What is this article?
Degassing closure, PP, red, PTFE insert, GL 45, 10 unit(s) is the article on this page. Luminix Health distributes KAUTEX for laboratory use. It sits in Screw caps & closures, inside Stoppers, caps & closures, in Matériel de laboratoire.
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.
