Aquastar® Lactose Standard 5%

The Aquastar lactose standard is a solid standard with a water content of about 5%. The batch-specific Certificate of Analysis states the exact value measured in the respective batch. The lactose standard can be applied universally. Due to its ease of solubility in methanol and its water content, this standard is suitable as a solid standard for both coulometric, and volumetric Karl Fischer titrations. It is especially suitable if the working medium used consists of solvent mixtures in which sodium tartrate dihydrate is only slightly soluble. This standard can also be used as an oven standard for a temperature range of 140-160°C.
