Karl Fischer Titrator - Volumetric & Coulometric KF Moisture Analyzer - 3 µg-250 mg Water

The Master Science Karl Fischer Titrator brings volumetric and coulometric KF titration together in one instrument, so the same unit can measure percent-level water and trace moisture down to a few micrograms. A 7-inch high-contrast touchscreen guides each method from titer determination to the final result.

Oven sampling is supported for solids, gases and samples that do not dissolve readily, and a sealed solvent manager handles filling, draining and burette cleaning safely.

Key Benefits

• One instrument, two techniques: the Master Science Karl Fischer Titrator switches between volumetric and coulometric KF without a second unit.
• Trace and high moisture covered: water from 3 µg to 250 mg is measured with ≤ 0.3 % repeatability.
• Safer reagent handling: the solvent manager uses leak-proof and anti-spill bottles.
• Accurate results: automatic drift compensation corrects for moisture ingress.
• Compliance support: user levels, GMP logs and GLP storage track every result.

Common Laboratory Problems and How This KF Titrator Helps

How the Master Science Karl Fischer Titrator helps with typical moisture testing problems:

• Need for two separate KF instruments: both techniques run on one unit.
• Spills of KF reagents: sealed solvent handling protects staff.
• Drift from ambient humidity: automatic drift correction keeps results accurate.
• Insoluble samples: oven sampling releases water before titration.
• Data integrity requirements: GMP logs and user control are available.
