Description
Screw-retaining devices for SBW glass cock plugs provide a complete three-part fastening solution sized NS 12.5 with GL 8 thread. These retainers secure the cock plug firmly in the stopcock barrel, preventing unintended loosening during operation while still permitting smooth rotation for flow control. Designed specifically for SBW-glass cock-plug systems, the assembly keeps the ground-glass sealing surfaces correctly seated under laboratory conditions. The complete 3-part set simplifies installation and replacement on compatible glass stopcocks used in distillation, vacuum work, gas handling and general wet chemistry. Supplied as 10 pc(s) per pack from manufacturer DWK Life Sciences, the devices support efficient servicing of multiple apparatus or stocking of common maintenance parts. Lightweight at approximately 0,001 kg per pack, they are easy to store alongside other glassware accessories. Suitable for research, analytical and teaching laboratories that employ NS 12.5 / GL 8 stopcock configurations, the retainers help maintain reliable, leak-resistant performance of SBW glass cock plugs throughout repeated use.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Screw-retain. device, SBW-gl. cock plugs, NS 12.5, GL 8, 3-part, complete
What is this article?
Screw-retain. device, SBW-gl. cock plugs, NS 12.5, GL 8, 3-part, 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.
