A very compact profile analysis tensiometer to measure surface and interfacial tension of liquids.
The PAT-1P is a highly compact, manual instrument developed for the precise measurement of surface and interfacial tension in liquids. Operating on the analysis of pendent and sessile drops—as well as buoyant and captive bubbles—the device provides reliable data for both liquid characterization and contact angle measurements on solid surfaces.
Developed for simplicity and portability, the instrument requires no external power supply and is powered entirely via USB. Its intuitive manual operation and robust functional range make it an ideal solution for educational purposes and fundamental laboratory research.





Very compact profile analysis tensiometer
Simple manual instrument to measure surface and interfacial tension of liquids
Contact angle measurements are available in the basic version
No power supply needed (powered by USB)
Ideal instrument for educational purposes
The principle is based on the analysis of the profile of pendent and sessile drops or buoyant and captive bubbles.
PAT-1P is well suited to determine the contact angle of liquids on solid surfaces.
