Description
Single way stopcock with SBW-glass cock plug is a laboratory glass component for controlled single-path flow in distillation, extraction and general glass apparatus. It is specified with DURAN® glass, a joint of 14.5, a pipe diameter of 9 mm and a bore of 2,5 mm, giving a compact stopcock geometry suited to modular glass lines. This unit from manufacturer DWK Life Sciences is intended for laboratory glass, vessels and consumables work where a reliable open/close element is required in glass stopcock assemblies. Supplied as 1 pc with a weight of 0,001 kg, it is practical as a spare or as a building block when constructing or maintaining glass manifolds and process connections. The SBW-glass cock plug forms the sealing interface for routine shut-off duties. Dimensional alignment of joint, pipe and bore supports integration into existing DURAN®-compatible setups used in research and analytical laboratories. Typical placement is within glass components for distillation and extraction trains that need precise single-way control without multi-port complexity.
This article is part of Rubber & silicone stoppers, in Stoppers, caps & closures.

Questions about Single way stopcock, SBW-glass cock plug, DURAN®, joint 14.5, pipe-Ø 9mm
What is this article?
Single way stopcock, SBW-glass cock plug, DURAN®, joint 14.5, pipe-Ø 9mm 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.
