Karl Fischer Titrators in Israel | BioAnalytics

Need a Karl Fischer titrator in Israel for water-content determination? Karl Fischer is the reference method for moisture in solids, liquids and gases — volumetric for higher water (~0.1%–100%) or coulometric for trace water (~1 ppm–5%). BioAnalytics supplies both, with the right electrode, reagent and method, plus installation, training, service and ISO 17025-accredited calibration.

Volumetric vs coulometric

Parameter	Volumetric	Coulometric
Water range	~0.1% – 100%	~1 ppm – 5%
Best for	medium/high water	trace water
Typical samples	food, chemicals, liquids	solvents, oils, dry raw materials
Sample introduction	direct / dissolution	direct / oven

Method essentials

KF uses a double-platinum polarized electrode for endpoint detection. Difficult samples use the oven method; accuracy is confirmed against a water standard and by proper titer determination. Interfering matrices (ketones, aldehydes) require reagent selection.

FAQ

Volumetric or coulometric — how do I choose?

Volumetric suits higher water content (~0.1%–100%); coulometric suits trace water (~1 ppm–5%). We choose based on your sample and expected water level.

When is the oven method needed?

When the sample is insoluble in the reagent or releases water slowly — the oven heats the sample and carries the moisture to the cell in dry gas. Common for plastics and difficult solids.

What about interferences?

Ketones, aldehydes and some sample types interfere; the right reagent and method avoid errors. Water-standard verification confirms accuracy.

Do you calibrate KF titrators too?

Yes — BioAnalytics is the only ISO/IEC 17025-accredited titrator & burette calibration lab in Israel (PJLA/ILAC-MRA).
