Force Tensiometer
Fully automated measurements of surface and interfacial tension for quality control
The K100C Force Tensiometer is a fully automated instrument for routine tasks, but also demanding measurements in quality control. The instrument's precision force sensor and the accurately shaped measuring probes ensure reliable results of the surface tension and interfacial tension.
Uniform procedures based on measurement templates of the ADVANCE software provide for user-independent results. Measurement preparation is quick and easy thanks to the user-friendly design and the intuitive control of the instrument’s components.

The combination of automation, precise force measurement and the absolute standardization of the measuring procedures is what makes the K100C ideal for quality control. The measuring methods run with prepared templates of the ADVANCE software in order to repeat the instrument’s behavior down to the smallest detail, reducing user intervention to a minimum.
The highly accurate contours of our ring and plate measuring probes also contribute to the reliability of the K100C. To ensure the accuracy of raw data for the detected force in different environments, the force sensor can be adjusted using an external precision weight.
Thanks to the large sample chamber, the sample is loaded quickly and conveniently into the instrument. Magnetically locking glass swing doors shield the force measurement from troublesome air currents. The closing of these doors is electronically recognized and can trigger the next automation step in order to speed up the measuring procedure.
As a supplement to the software control, the instrument's intuitive keyboard ensures easy operation of the sample stage and other components, such as the lighting.
Optional thermostat jackets provide for measurements under consistent conditions. They can also be used for high or low temperatures to give a realistic picture of the sample’s behavior in the actual process. When testing dispersions, an integral magnetic stirrer, which can also be used in an automation, ensures that the sample is homogenous before the measurement is carried out.
Our specially developed Micro Dispensers equip the K100 for measuring the critical micelle concentration (CMC) with the utmost precision. The surfactant concentration range is set up and then measured fully automatically.
With the high temperature solution TJ60, precise surface tension and contact angle data of hot liquids such as polymer melts or bitumen are easily accessible. The unit quickly heats up the sample to reach and keep a stable target temperature
