Surface Tension Measurement

The flexible tensiometer for routine quality assurance

Our Force Tensiometer – K20 is a robust, semi-automatic instrument for the precise measurement of surface tension and interfacial tension. Using the ring and plate method as the main tensiometric methods, it produces reliable measurements for the routine quality assurance of your surfactant solutions and interfacial processes.

Tasks and applications

■ Determination of the effectiveness of wetting agents

■ Checking the surfactant content in solutions below the critical micelle concentration (CMC)

■ Tank clearance and cleaning validation in the foodstuffs industry

■ Measurement of interfacial tension for the quality assurance and optimization of emulsifiers

■ Analyzing the aging status of oils according to ASTM D 971 and IEC 62961

 

Measuring methods and options

■ Surface tension using the ring and plate method

■ Interfacial tension using the ring and plate method

■ Surface tension and interfacial tension using the ring tear-off method

■ Measuring the density of liquids

■ Temperature control from ‑10 to 130 °C, temperature measurement with external sensor
