Aquastar® Water Standards in Ampoules

In our Aquastar® range of standards for Karl Fischer titration, we offer various liquid water standards in easy-to-use ampoules. All of these standards consist of high-quality solvent mixtures featuring defined water contents – 1 %, 0.1 %, and 0.01 %. Water standard 1 % is recommended for volumetric titer determination using one-component and two-component reagents. The two water standards 0.1 % and 0.01 % are suitable for coulometric titration.

All Aquastar® water standards in ampoules are tested against standard reference materials from NIST (National Institute of Standards and Technology, Gaithersburg, USA). Each package contains a batch-specific certificate with the exact measured water content of the batch, uncertainty data, measuring method, the NIST batch, and minimum shelf-life.

These Certified Reference Materials (CRMs) are manufactured under the scope of ISO 17034 and certified in an ISO/IEC 17025 accredited testing lab, ensuring unparalleled accuracy and reproducibility.
