Hydranal-Coulomat Reagents provide highly accurate measurements of trace amounts of water and have a shelf life of up to five years. Choose Hydranal-Coulomat AG-Oven for Karl Fischer titrations with an oven or Hydranal-Coulomat AG for cells without diaphragms.
Hydranal-Composite is the most frequently used pyridine-free Karl Fischer titrating reagent. It offers unlimited water capacity and the greatest flexibility for media, including methanol-reacting compounds (ketones and aldehydes). Choose from a range of media options, some with special solvents, for fats, oils, and other specific materials or needs.
