Tensiometry is the measurement of interfacial tension, typically of the interface between a liquid and a solid, gas or another liquid.
EAG Laboratories performs dynamic contact angle and force tensiometry measurements using the Dataphysics DCAT21. The DCAT21 is equipped with a high precision balance and z-axis variable speed stage for reproducible measurements of the change in apparent mass of a sample when in contact with a liquid. All measurements can be performed under temperature-controlled conditions from -20ºC to 100ºC.
