Description
Hexagonal hollow stopper with short ground joint NS 10/13 is a glass laboratory stopper intended for sealing vessels fitted with matching NS sockets. The stopper is hollow and flat-topped, with a hexagonal head that affords a secure grip for insertion and removal by hand. As a short-ground version it offers a compact closure for flasks, bottles and other glassware carrying an NS 10/13 joint. This stopper from manufacturer Witeg is manufactured from glass and is suitable for routine laboratory sealing tasks where a reliable ground-joint fit is required. The hexagonal profile allows convenient tightening without tools, while the hollow body keeps the mass low. It is appropriate for general chemical work involving aqueous solutions, organic solvents and other media compatible with glass stoppers. Supplied as a single piece, the NS 10/13 short hollow stopper integrates directly into standard jointed glassware assemblies used in analytical, preparative and teaching laboratories.
This article is part of Ground-joint glass stoppers, in Stoppers, caps & closures.

Questions about ST-glass stopper, short joint, ST 10/13
What is this article?
ST-glass stopper, short joint, ST 10/13 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.
