Contact Angle Measuring Instrument EasyDrop

DSA15E

EasyDrop

All the parameters of the liquid and solid surface tension are determined precisely by the EasyDrop DSA15E. Analysis of the pendant drop provides the surface and interfacial tensions of liquids. Various contour analysis methods are included for determining the contact angle. The software calculates the surface free energy according to all the usual models.
