Interfacial Tension

Interfacial Tension Meter

Manufacturer: Vinci Technologies
Model Number: IFT-700

The apparatus allows for the determination at reservoir conditions of interfacial tension between liquid-gas and liquid-liquid interfaces using pendent drop method as well as the contact angle between liquid and solid interfaces using sessile drop method. A liquid drop is created and put in contact with gas or solid in a cell at reservoir conditions. A camera connected to a computer records the shape of the liquid drop to derive the interfacial and contact angle properties. The Drop Analysis System software allows the fast calculation of surface and interfacial tension of pendent drop and contact angles of sessile drops.
