The viscometer is intended for the studies of the phase boundary of immiscible liquids in the field of petroleum chemistry, colloidal chemistry, and biochemistry.

The viscometer can be used to measure the boundary tension in liquid-liquid systems, to determine the viscosity of dispersed systems and layers formed at the phase boundary, as well as to determine the viscosity of the volumes of the phases under contact and single-phase liquids. 

The viscometer is indispensable in the study of emulsions and microemulsions at the control of oil-displacing liquids. The device uses the method of the scanning viscometry, whose principle consists in a large-scale movement of the vibration probe of the viscometer. During the probe displacement through the phase boundary a maximum of mechanical resistance is observed, whose shape and amplitude depends on the parameters of the phase boundary.
