Description
Stopper with valve stopcock NS 19/26 SVS hose coupling is a specialized laboratory glassware component featuring a standard ground joint NS 19/26, an integrated valve stopcock, a bent tube and an SVS hose coupling. This design permits precise flow control while enabling secure hose attachment through the SVS interface (0.185.001) and directional routing via the bent tube. Provided as a single piece with a net weight of 0,03 kg and corresponding gross weight of 0,03 kg, it is suited for incorporation into glass apparatus requiring combined stopcock, hose and tube functionality. Typical use includes distillation setups, reaction systems and fluid or gas transfer lines in chemical laboratories. Manufactured by Witeg, the fitting belongs to the group of transition pieces and screw couplings compatible with normschliff glassware. The standardized NS 19/26 joint ensures ready interchangeability with other matching laboratory components. Its construction supports reliable sealing and connection integrity under ordinary laboratory conditions. Originating from Germany, this stopper offers a practical solution for research and analytical applications that demand adjustable valve control together with SVS hose coupling and a bent-tube outlet.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Suction tube, with needle valve stopcock
What is this article?
Suction tube, with needle valve stopcock is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Ground-joint glass stoppers, inside Stoppers, caps & closures, in Labware.
A ground-glass stopper matches a ground neck of a stated joint size. A 14/23 stopper does not seal a 29/32 neck. The stopper is part of the flask's seal, and a chip on the grind is a leak.
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.
