Optical Tensiometer

Optical tensiometry can be used to precisely measure the contact angle of water or other liquids on the surface of a given solid substrate allowing you to better characterize your material surface properties such as wettability, adhesion, roughness, printability, as well as for troubleshooting purposes.   


The Biolin Scientific ThetaLite 101 tensiometer is a Windows-7 controlled instrument used in correlation with the OneAttension software for data capture and analysis.  The high resolution digital camera with recording capabilities allows for analysis of contact angle even for fast absorbing samples.
