Interfacial Tension Meter

Interfacial Tension Meter

Manufacturer: Vinci Technologies
Model Number: IFT-700

The robust yet precise IFT700 apparatus can determine at reservoir-representative conditions of pressure and temperature, both the interfacial tension of two immiscible fluids using the pendant/rising drop methods and the contact angle of a liquid droplet on a solid surface using the sessile drop method. By means of a capillary needle, a droplet (drop fluid) is formed in a chamber containing the other fluid (bulk fluid), subjected to the desired pressure and temperature conditions. A state-of-the-art image capture and processing system computes the relevant geometric parameters to derive the interfacial tension using the Laplace equation. The process is similar to the interfacial tension with the additional step of depositing the droplet on a planar solid surface. Upon reaching equilibrium, the contact angle can directly be measured with the Vinci interpretation software.
