Description
Cock plugs in SBW glass are precision glass components for standard ground joints size 18.8, equipped with a larger borehole diameter of 6 mm. Intended as the rotatable core of laboratory stopcocks, they enable controlled regulation of liquids and gases in distillation trains, vacuum manifolds, extraction setups and general process glassware. SBW glass provides a robust ground sealing face that mates with corresponding stopcock barrels for dependable closure. The 6 mm borehole offers increased flow capacity compared with narrower plugs, making these parts suitable where higher throughput is needed while still allowing straightforward cleaning. Supplied in packs of 2 pc(s) from manufacturer DWK Life Sciences, the plugs are practical for maintenance, apparatus construction or spare-part inventory. Pack weight is approximately 0,076 kg. They fit glassware systems based on standard ground joint 18.8 and support consistent, leak-tight performance in research, analytical and teaching laboratories that rely on classic glass stopcock technology for everyday fluid handling.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cock plugs, SBW glass, for st. gr. joint 18.8, borehole Ø 6 mm, 2 unit(s)
What is this article?
Cock plugs, SBW glass, for st. gr. joint 18.8, borehole Ø 6 mm, 2 unit(s) 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.
