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.

Water standard oil 15 - 30ppm is especially designed for users who need to measure the water content in oil samples. The water standard exactly corresponds to the low water content and the matrix of oil samples and the exact value for each batch is stated in the certificate. Practical ampoules ensure ease of handling.
