Karl Fischer Reagents -  Aqualine^®

 

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.
