摘要
System for determining the surface tension of a solution that is in a container, in particular a solution of surface active agents (washing liquid 1), according to the bubble pressure procedure, being introduced into the solution by means of a capillary (4) a gastric volumetric current and considering during the bubble formation the evolution in time of the pressure of this volumetric current, characterized in that the capillary (4) flows into a bubble chamber (2) in which a column can be generated by depression of liquid that rises above the height where the capillary ends (4).
