Hydranal® Reagents for Karl Fischer Titrators:



One Component Volumetric Reagents | Two Component Volumetric Reagents Coulometric Reagents | Hydranal Standards | Return to Products



Hydranal® Reagents from Riedel de Haen are patented formulations of Karl Fischer reagents for water determination by either volumetric or coulometric procedures. Hydranal® reagents deliver accurate results with rapid titration and stable end points. Most of these reagents are also free of halogenated hydrocarbons and 2-methoxyethanol. Use this guide to choose the Hydranal® reagents for your application.


One Component Volumetric Reagents:


Hydranal Composites contain all the reactants (Iodine, sulphur dioxide and imidazole) dissolved in diethyleneglycolmonomethyl ether (degee). The loss of titre is less than 10% per year. Volumetric reagents have a two-year minimum shelf life for an unopened bottle.
