Item Code test : DVT 50 Drop Volume Tensiometer

DVT50: The effect of a surfactant as an emulsifier is based on the fact that it reduces the interfacial tension between phases which do not easily mix. As surfactants need a certain time to do this, the effect of an emulsifier depends on the mixing dynamics. With DVT50, you can measure the speed with which emulsifiers produce their effect and reduce the interfacial tension. 

Whether pumping, stirring or flooding: oil-water interfaces are always in motion. The drop volume technique of the DVT50 from KRÜSS records the interfacial tension under dynamic conditions – in an interface age range from fractions of a second up to several minutes.
