Description
DURAN® hollow stopcock plug with thread, glass handle and 3-part stopcock retainer is a ground hollow plug intended for laboratory stopcocks that demand reliable sealing under changing conditions. The hollow design with integrated thread and glass handle is well suited to work involving temperature fluctuations and elevated tightness requirements. Supplied complete with the matching three-part stopcock retainer, it secures the plug firmly in the barrel. Manufactured from borosilicate glass 3.3 by Duran/DWK Life Sciences, the component offers the chemical and thermal durability expected of DURAN® laboratory glassware. Sized for NS 18,8 joints, the plug supports grease-compatible or higher-demand sealing applications in glass apparatus. With a net weight of 0,017 kg it remains practical for routine assembly. Typical use includes securing hollow DURAN® plugs where temperature variation and improved tightness are important for consistent flow control in chemical and analytical setups.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about DURAN® Stopcock Key, threaded glass handle, with three part retaining device
What is this article?
DURAN® Stopcock Key, threaded glass handle, with three part retaining device 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.
