Force Tensiometer – K6 – Krüss

The K6 Force Tensiometer by Krüss is used for accurately determining surface and interfacial tension using the ring tear-off method. It is ideal for working with surfactant solutions and solvents, offering simplicity and efficacy in its operation. This instrument also serves as an educational tool to illustrate the principles of surface tension force.

This manual instrument employs a calibrated torsion wire and measuring ring system to demonstrate surface and interfacial tension. The drag pointer mechanism then provides immediate and precise readings of the force required to detach the ring from the sample surface.

The K6 Tensiometer has a footprint of 230 mm by 270 mm (W × D) and stands 315 mm tall. It weighs 3 kg without accessories, making it both compact and portable for various environments.

Yes, the K6 Tensiometer requires external calibration for accurate force measurement. Though calibration weights (CP11 or CP12) are optional, they are recommended to ensure the instrument’s precision and reliability.

Yes, equipped with a Du Noüy ring, the K6 Tensiometer is capable of measuring both surface tension and interfacial tension. Its measurement range is between 1 to 90 mN/m, with a resolution of 0.5 mN/m, utilizing a linear correction method for accuracy.

Several features enhance the K6's usability, including a built-in bubble level for ensuring the instrument's proper alignment and a simple platform with a travel distance of 85 mm. These design elements contribute to the K6’s ease of use and operational efficiency.

Krüss offers a range of online courses and webinars aimed at expanding your understanding and practical skills in surface science. Additionally, we provide comprehensive technical services to ensure you are getting the most from your K6 Tensiometer, including setup, installation, training, maintenance, and repair.
