Description
DURAN® sealing plug with 1/4'' - 28 thread in ETFE is an ETFE blank stopper intended for HPLC dispensing caps with GL 45 thread and fitted with three plug olives. The chemically resistant ETFE body supports blanking of unused ports while maintaining a secure fluid path. It is used for solvent feeding to HPLC systems and for the safe transfer of liquid media inside a closed and sterile system. The 1/4'' - 28 thread matches common HPLC tubing and cap interfaces, allowing straightforward installation on multi-port GL 45 assemblies. Supplied as one piece with a net weight of 0,001 kg and a gross weight of 0,003 kg, the component is non-sterile and suited to routine analytical workflows. This accessory from manufacturer Duran/DWK Life Sciences helps keep solvent lines sealed when ports are not in use, reducing the risk of contamination or evaporation during continuous or intermittent HPLC operation. Its compact form and chemical resistance make it a practical spare or replacement part for laboratory solvent-delivery setups that rely on GL 45 HPLC bottle caps.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about DURAN® Sealing Plug, with 1/4” - 28 thread, ETFE
What is this article?
DURAN® Sealing Plug, with 1/4” - 28 thread, ETFE is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Rubber & silicone stoppers, inside Stoppers, caps & closures, in Labware.
A rubber or silicone stopper is pushed into a mouth. The size number corresponds to a top and bottom diameter. Silicone survives higher temperatures and more autoclave cycles. Natural rubber is attacked by oils and by some solvents.
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.
