Description
Iodine flask 250 ml NS 29/32 with funnel is a laboratory glassware item intended for iodine value determinations and related analytical procedures. The flask is manufactured from DURAN tubing in borosilicate glass 3.3 and carries a ground joint NS 29/32. It is supplied with a funnel and an NS hollow stopper with a long stem, supporting controlled reagent addition and secure closure during sample work-up or titration. Nominal volume is 0,25 l and net weight is 0,17 kg, offering a practical mid-range capacity for routine bench work. This iodine flask from manufacturer Witeg is used for volumetric and wet-chemistry tasks in analytical and quality-control laboratories. The transparent borosilicate body allows visual observation of colour changes typical of iodine-based assays, while the NS 29/32 joint ensures compatibility with standard ground-joint stoppers and adapters. Suitable for fat and oil characterisation as well as general titration workflows, the vessel provides reliable geometry and joint fit. Pack size is one piece, ready for integration into existing laboratory glassware sets where DURAN-based borosilicate construction is preferred.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Iodine flasks 250 ml ST 29/32 with funnel
What is this article?
Iodine flasks 250 ml ST 29/32 with funnel 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.
