How to Choose the Right Karl Fischer Titrator

Choose Coulometric Karl Fischer Titration for Trace Moisture

KFT-20V/ KFT-41C / KFT-50C coulometric karl fischer titrations are recommended when the sample contains very low water content. They are commonly used for oils, solvents, gases, petroleum products, high-purity chemicals and other low-moisture samples.

Best for:

  • Trace water analysis
  • Low-moisture samples
  • Solvents and oils
  • High-purity chemicals
  • Samples requiring μg-level moisture detection

Choose Volumetric Karl Fischer Titration for Routine Moisture Testing

KFT-40C / KFT-41V/ KFT-50V volumetric karl fischer titrations are suitable for samples with higher moisture content. They are often used for pharmaceuticals, chemicals, food ingredients, powders, raw materials and routine quality control samples.

Best for:

  • Routine water content testing
  • Raw material inspection
  • Pharmaceutical and chemical QC
  • Samples with mg-level moisture content
  • Laboratories requiring repeatable daily testing

Choose Volumetric + Coulometric Models for Flexible Testing

If your laboratory handles different sample types and moisture levels, a combined karl fischer titrator （KFT-40VC / KFT-50VC） can provide more flexibility. One system can cover both routine water content testing and trace moisture analysis.

Best for:

  • Laboratories testing both high and low moisture samples
  • Multi-application QC labs
  • Research laboratories
  • Pharmaceutical and chemical testing centers
  • Users who want one instrument for broader testing needs

FAQ

Volumetric Karl Fischer titration is more suitable for samples with medium or higher water content, while coulometric Karl Fischer titration is better for trace moisture measurement. If your laboratory tests both types of samples, a combined model such as KFT-40VC or KFT-50VC is recommended.

For trace moisture analysis, Drawell offers coulometric models such as KFT-20V, KFT-41C and KFT-50C. The KFT-50C provides a wider advanced range from 3 μg to 200 mg and is suitable for laboratories requiring higher performance and better data management.

For routine quality control, volumetric models such as KFT-40C, KFT-41V and KFT-50V are suitable. They are designed for regular water content testing in raw materials, chemicals, pharmaceuticals and food-related samples.

If your laboratory tests samples with both low and higher water content, choose a combined volumetric and coulometric model. KFT-40VC is suitable for flexible routine testing, while KFT-50VC is better for advanced laboratories requiring stronger data management and broader application coverage.

Yes. Selected Drawell models support oven sampling methods, which can be used for solids, powders and samples that are difficult to dissolve directly in the titration vessel.

Karl Fischer titration directly measures water content and is generally more selective for moisture than drying methods. It is especially useful when samples contain volatile substances or when high sensitivity is required.

Yes. Depending on the model, Drawell Karl Fischer titrators can support RS-232 printing, USB communication, U disk data export, CSV export and PDF export. Higher-end models also support more advanced data and method management.

Selected models support GLP-compliant data storage, user management, method management and GMP-related functions. KFT-50 series models are more suitable for laboratories with stricter data traceability requirements.

KFT-40VC is suitable for laboratories that need both volumetric and coulometric testing at a practical routine level. KFT-50VC is more suitable for advanced laboratories that require higher sensitivity, stronger data management, GMP-related functions and larger data storage capacity.
