Description
Replacement stopper NS 24/29 for iodine flask is a precision ground-joint stopper intended as a direct spare part for matching iodine flasks. The stopper features the standardised joint size NS 24/29, ensuring compatibility with iodine flasks that use this common laboratory ground joint. With a net weight of 0,026 kg and a gross weight of 0,026 kg, the component is lightweight yet dimensionally stable for repeated laboratory use. This replacement stopper from manufacturer Witeg restores a tight, reliable seal on iodine flasks after wear or breakage of the original stopper, supporting continued accurate work in volumetric and titration procedures. Categories include standard ground-joint stoppers and plastic stoppers, reflecting its role as a dedicated spare for iodine-number glassware. Supplied as one piece, it is ready for immediate exchange without modification of the receiving flask. The NS 24/29 geometry guarantees interchangeability within the corresponding joint system, making the stopper a practical maintenance item for analytical laboratories that rely on iodine flasks for routine determinations.

Questions about SPARE STOPPER NS 24/29, FOR IODINE-FLAS
What is this article?
SPARE STOPPER NS 24/29, FOR IODINE-FLAS is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Erlenmeyer flasks, inside Beakers & flasks, in Labware.
An Erlenmeyer, or conical, flask has a flat base and a narrowing wall so a liquid can be swirled. It is the ordinary culture and titration flask. A baffled wall is a different article, used when the swirl must turn the liquid over.
A beaker is an open working vessel: easy to pour, poor as a measure. An Erlenmeyer flask has a flat base and a conical wall so a liquid can be swirled without climbing out. A round-bottom flask is for heating under a condenser, because the heat meets a curved wall and the joint at the neck connects to the rest of the glassware. Borosilicate is the glass that survives the temperature change. These forms are listed under ISO laboratory glassware.
