Description
Cock plugs in SBW glass for standard ground joint 12,5 with a borehole diameter of 2 mm are precision glass stopcock components intended for laboratory glassware assemblies that use this joint size. Manufactured as matching plugs for stopcocks, they provide the interchangeable sealing element needed when building or servicing ground-joint apparatus in chemical and analytical workflows. Each plug is specified for standard ground joint 12,5 and features a 2 mm borehole, supporting controlled flow paths in stopcock bodies designed around that geometry. The set is supplied as 2 pc(s), giving a practical pair for installation, spare holding or parallel setups. With a pack weight of 0,03 kg, the items remain light and easy to handle during assembly or replacement. SBW glass construction aligns with conventional laboratory glassware practice for stopcock plugs used on joints of this size. These cock plugs from manufacturer DWK Life Sciences address the need for correctly dimensioned glass plugs when maintaining or configuring stopcocks on standard ground joint 12,5 apparatus with a 2 mm bore.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

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