Aquastar®- our new global Karl Fischer product line

We are proud to present our global product range of Karl Fischer reagents and standards now under the brand name Aquastar. In North America Aquastar is already a very well-known and established high quality brand. The existing Apura® trademark will be replaced with the trademark Aquastar outside of North America. To offer one global product line available worldwide we will use the brand name Aquastar for all our Karl Fischer products.

All products will keep the same catalogue numbers, designation, composition, quality and performance. Outside of the United States and Canada, we simply changed the brand name to Aquastar - nothing more.
