Description
Hollow stopper NS 10/19 brown tinted is a hexagonal standard-taper stopper intended for secure closure of laboratory glassware with matching NS joints. Produced in accordance with DIN 12252, it incorporates a drip tip that supports controlled drainage and minimises residual liquid upon removal. Brown tinting offers light protection for sensitive media and makes the stopper easy to distinguish among other fittings. This hollow stopper from manufacturer Witeg provides a reliable seal for flasks, bottles and related apparatus equipped with NS 10/19 ground joints. The hexagonal head facilitates firm handling and seating without additional tools. Lightweight and compact, it suits everyday sealing duties in chemical, analytical and teaching laboratories. Supplied as a single piece, it integrates readily into standard borosilicate glassware setups that depend on precise NS connections for consistent, leak-resistant performance.

Questions about Hollow stoppers ST10/19 amber stained
What is this article?
Hollow stoppers ST10/19 amber stained 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.
