Soft Materials Lab - B606
Primary Training Contact

The Ramé-hart Model 290 Automated Goniometer / Tensiometer offers a powerful level of automation and a wide array of software tools. The system includes our software-driven Automated Tilting Base for measuring advancing, receding, and roll-off angles as well as contact angle hysteresis. The Surface Tension Tool permits the measurement of both surface tension as well as interfacial tension on pendant and sessile drops. A database of liquids is included and can be added to using the phase editor. Critical drop dimensions and volume are also reported. All results are logged and can be exported to other programs.
