Description
Stopcock retainer, 3-part and complete, secures threaded stopcock plugs of SBW-J glass inside the stopcock barrel. Designed for NS 12,5 joints with GL 8 thread, the three-part screw locking assembly holds the plug firmly in place and prevents unintended loosening during laboratory work. It is intended for use with ground DURAN® single-use stopcocks and compatible threaded SBW-J plugs, providing higher operational safety through positive mechanical retention. The complete retainer from manufacturer Duran/DWK Life Sciences simplifies mounting and contributes to the overall integrity of the stopcock system under typical chemical and analytical conditions. Constructed for reliable performance in fluid-handling setups, it supports applications ranging from routine reagent transfer to more demanding titration and process work. Offered as 1 pc, the unit is ready for immediate installation or replacement, ensuring laboratories can maintain secure, leak-resistant stopcock assemblies with minimal downtime. Its three-part design delivers straightforward assembly while meeting the retention requirements of precision ground-glass apparatus.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Three part retaining device for Stopcock Key threaded, SBW-J glass, complete
What is this article?
Three part retaining device for Stopcock Key threaded, SBW-J glass, complete 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.
