Description
Iodine flask 250 ml is a specialised Sendtner iodine flask with a nominal volume of 0,25 l, designed for iodine value determinations and related titration work in analytical chemistry. It features an NS 29/32 ground joint together with a matching NS hexagonal hollow stopper that ensures a secure seal during reactions and temporary storage of iodine-containing solutions. The robust glass construction supports accurate volumetric handling and safe manipulation of reagents. With a net weight of 0,146 kg the flask remains convenient for routine bench use. Supplied as 1 piece from manufacturer Witeg, this iodine flask serves food chemistry, oil analysis and pharmaceutical testing laboratories where precise iodine number measurements are required. The Sendtner geometry promotes thorough mixing and complete contact between sample and reagent, which is essential for reliable endpoint detection in iodometric titrations. Compatibility with standard laboratory glassware systems allows seamless integration into existing workflows for fat and oil characterisation or other halogenation assays.
This article is part of Erlenmeyer flasks, in Beakers & flasks.

Questions about Iodine determination flask, Sendtner, 25
What is this article?
Iodine determination flask, Sendtner, 25 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.
