Description
Quick-release closures GLS 80 are laboratory bottle closures moulded from polyarylsulphone plastic for secure sealing of GLS 80 neck vessels. Each closure measures Ø 86 × H 40 mm and is designed for rapid open-and-close handling on wide-neck laboratory bottles, media bottles and storage containers used in sample preparation, buffer storage and general wet-lab workflows. The polyarylsulphone construction suits routine laboratory environments where chemical resistance and mechanical stability of the closure are required. Supplied in a practical pack of 5 pc(s) with a total weight of 0,175 kg, the set supports multiple bottle stations or spare inventory on the bench. These closures (DWK Life Sciences) fit the GLS 80 thread system commonly found on laboratory glass and plastic bottles, making them a straightforward accessory for seals, hose connectors and container systems. They integrate cleanly into existing labware setups for containers, bottles and canisters without altering established bottle formats. Ideal for laboratories that standardise on GLS 80 openings and need reliable quick-release lids for daily handling, transfer and short-term storage tasks.

Questions about Quick-release closures GLS 80, Polyarylsulphone plastic, Ø 86 x H 40mm
What is this article?
Quick-release closures GLS 80, Polyarylsulphone plastic, Ø 86 x H 40mm 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.
