Description
Cock plugs in SBW glass for standard ground joint 12,5 with a borehole diameter of 2,5 mm serve as interchangeable glass stopcock plugs for laboratory apparatus built on this joint standard. They are intended for stopcock assemblies where a slightly larger bore is required while retaining compatibility with standard ground joint 12,5. The 2,5 mm borehole defines the internal passage through the plug, supporting flow control in glass systems that specify this bore size. Supplied as 2 pc(s) per pack, the set is convenient for fitting, replacement or keeping a matched spare on hand. Pack weight is 0,001 kg, reflecting the compact glass format of the plugs. SBW glass is the stated material, consistent with common laboratory stopcock plug practice. Correct joint and borehole pairing helps maintain reliable seating and flow geometry in ground-joint glassware. These cock plugs from manufacturer DWK Life Sciences provide the specified SBW glass plugs for standard ground joint 12,5 applications that call for a 2,5 mm borehole in stopcock configurations.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Cock plugs, SBW glass, f. st. gr. joint 12.5, borehole Ø 2.5 mm, 2 unit(s)
What is this article?
Cock plugs, SBW glass, f. st. gr. joint 12.5, borehole Ø 2.5 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.
