仪器简介：
Classical method to measure the surface and interfacial tension of
liquids,principle is based on the accurate determination of the volume
of drops detaching from circular capillaries.
Features of the instrument surface and interfacial tension of liquids
dynamic interfacial tensions in a time range of less than one second
up to several minutes complements the profile analysis tensiometry at
short times, in particular for liquid/ liquid interfaces use with any
PC or laptop, no time-consuming filling procedure as it refills
automatically from a reservoir temperature controlled cell small size
and easy to handle correction of the viscosity effects at short drop
times.
