Description
Stopper with straight tube NS 19/26 with SVS is a specialized laboratory glassware fitting that unites a standard NS 19/26 ground joint, a straight tube section and an SVS hose coupling. This configuration allows secure attachment of flexible tubing while maintaining compatibility with conventional conical-joint apparatus. The component has a net weight of 0,017 kg and is offered as a single unit for flexible glassware assembly. Produced by Witeg, it falls within the range of transition pieces, reducing adapters and screw couplings employed in chemical laboratories. The combination of a straight tube and SVS coupling provides a convenient pathway for gas or liquid transfer without the need for a separate stopcock, supporting continuous-flow applications. The NS 19/26 taper ensures interchangeability with matching flasks, condensers and receivers. Ideal for synthesis, distillation and general fluid-handling setups, this stopper simplifies the construction of modular glass systems in research, industrial and teaching laboratories.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about Suction tube, straight, with SVS-hose c
What is this article?
Suction tube, straight, with SVS-hose c 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.
