Description
Ventilation screw caps GLS 80 are laboratory closures equipped with an ePTFE membrane and supplied in blue for clear visual identification on the bench. Intended for GLS 80 thread systems, these DURAN® caps support controlled gas exchange while helping limit particulate ingress during storage, incubation or media handling. The membrane design is suited to workflows that need pressure equalisation without fully opening the vessel, making the caps useful for culture media, buffers and other laboratory preparations kept in large-thread bottles. Each pack contains 2 pc(s) and has a total weight of 0,070 kg, offering a compact accessory set for routine glassware setups. Produced by DWK Life Sciences, the DURAN® ventilation screw caps integrate with matching laboratory bottles and vessels used in research, quality control and process support. Their combination of a robust screw-cap body and ePTFE membrane provides a practical sealing option wherever GLS 80 ventilation is required in daily laboratory practice.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Ventilation screw caps GLS 80, DURAN® with ePTFE membrane, blue, 2 unit(s)
What is this article?
Ventilation screw caps GLS 80, DURAN® with ePTFE membrane, blue, 2 unit(s) is the article on this page. Luminix Health distributes DWK Life Sciences 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.
