Fisher Chemical® – Aqualine® reagents for Karl Fischer Titration

Karl Fischer titration is an analytical application that is used to determine the water content/moisture in a variety of sample types: solids (food, drugs, soil, etc), liquids (beverages, oils/lubricants) and gases.
Fisher Chemical offer a complete range of Karl Fischer titration reagents designed to meet the needs of analytical chemist using a volumetric or coulometric titrator.


Product Features & Benefits:
Aqualine reagents for Karl Fischer titration by volumetry: Available as 1 or 2 components solution, pyridine free, fast & stable endpoints, formulation based on Sigma-Aldrich Hydranal formulation (using imidazole as base).
Aqualine reagents for Karl Fischer titration by coulometry : Innovative formulation, faster titration speed vs Sigma-Aldrich Hydranal reagents, long product shelf-life.

We have evaluated the performance of our Aqualine products and they displayed better results when compared to Sigma’s HYDRANAL products.


Aqualine Volumetric :

  • Faster titration speed vs. Hydranal equivalent
  • Similar water recovery performance

Aqualine Coulometry :

  • Faster titration speed
