Description
Stainless steel cap with GL 45 thread and PTFE gasket is a robust closure designed for laboratory storage bottles. The metal construction provides mechanical strength and durability for routine handling, while the integrated PTFE gasket supports a reliable seal at the bottle neck. GL 45 threading matches common laboratory bottle standards, enabling straightforward exchange or replacement of existing caps without adapters. Intended for use with storage bottles, this accessory helps secure contents during storage, transport within the lab, and everyday sample handling. Supplied as a single unit with a weight of 0,157 kg, it is a practical spare or upgrade component for metal-bottle workflows. The combination of stainless steel and PTFE is well suited to general laboratory environments where chemical resistance of the sealing face and long service life of the cap body are required. Available from manufacturer DWK Life Sciences, the cap fits neatly into labware setups involving containers, bottles, and related metal vessels. It supports organised storage of reagents and samples when paired with compatible GL 45 storage bottles in research, quality-control, and teaching laboratories.
This article is part of Screw caps & closures, in Stoppers, caps & closures.

Questions about Stainl. st.cap,GL 45 thread, PTFE gasket, for storage bottle, 1 unit(s)
What is this article?
Stainl. st.cap,GL 45 thread, PTFE gasket, for storage bottle, 1 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.
