Description
Screw caps GL 32 are laboratory screw closures made from blue polypropylene for secure sealing of bottles and vessels with a GL 32 thread. Rated for a maximum temperature of 140 °C, the polypropylene construction offers the toughness and chemical resistance needed for everyday heated and ambient laboratory work. Each pack contains 10 pieces, a practical quantity for equipping media bottles, reagent containers and process vessels in research, quality control and production settings. The standardised GL 32 thread ensures broad compatibility with common laboratory glassware and plastic bottles. These blue caps, from manufacturer Marienfeld, give clear visual identification on the bench while delivering a reliable mechanical seal for sample storage, buffer preparation and general liquid handling. They belong to the screw-closure and laboratory screw-cap category used across life-science and analytical workflows, supporting consistent vessel sealing without specialised liners or complex accessories. Ideal as routine consumables, they help keep organised inventories ready for daily sealing tasks on GL 32 systems.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Screw caps GL 32,
What is this article?
Screw caps GL 32, is the article on this page. Luminix Health distributes Marienfeld 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.
