Beschrijving
Screw caps GL 32 provide secure closure for laboratory bottles fitted with a GL 32 thread. Made from red polybutylene terephthalate (PBT), the caps are rated for a maximum temperature of 180 °C, supporting demanding bench and storage conditions where thermal and mechanical robustness matter. The red colour aids quick visual sorting among mixed bottle inventories in media kitchens, sample preparation areas, and general wet laboratories. Each unit is packed in sets of 10 pieces from manufacturer Marienfeld, making restocking straightforward for facilities that standardise on GL-thread bottle systems. PBT construction combines dimensional stability with good chemical resistance for routine aqueous and solvent-related laboratory use within the material’s performance envelope. These screw caps are suitable for sealing reagents, buffers, and process intermediates when a reliable GL 32 closure is required. Consistent thread geometry supports repeatable sealing performance across bottles of matching specification in analytical, biotech, and teaching laboratories.
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 Labmateriaal.
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.
