Surface and interfacial tensiometry
For this service we offer a Sigma 701 force tensiometer (Biolin Scientific) with software for control, acquisition and data treatment for the measurement of surface and interfacial tensions, as well as the automatic determination of critical micellar concentrations. It is equipped with Wilhelmy plate and Du Nouy ring accessories.
We also offer a SITE Spinning Drop Interfacial Tensiometer (Krüss) for determination of liquid-liquid interfacial tensions by the spinning drop method.
Customer benefits
