Within the European Union and worldwide, there is an increasing demand for more transparent and comparable analytical results. This is particularly true for water determinations according to Karl Fischer, it is therefore necessary to use reliable reference materials to ensure accurate results. The Aquastar® product line offers a series of excellent standards: in addition to their use in monitoring Karl Fischer equipment and performing titer determination of volumetric Karl Fischer reagents, they can also be used for checking measuring results in order to evaluate their accuracy. To ensure the highest quality, Aquastar® standards are manufactured under the strictest control and are accurately measured using validated procedures in our DIN EN ISO/IEC 17025 accredited calibration and testing laboratory for Karl Fischer titration.

Sodium tartrate dihydrate is the volumetric standard for Karl Fischer titration. Under normal conditions it is stable and non-hygroscopic. Sodium tartrate dihydrate has a stoichiometric water content of 15.66% and is primarily used for titer determination in volumetry.
