Zusammenfassung:	An apparatus for automatically determining the surface tension by the stalagmometer principle using a pipette containing a test volume, having a drop face at its lower end and is provided with three light barriers. The three light barriers are connected to an evaluation circuit which counts the number of whole drops and also determines the fractions of whole drops pertaining to the test volume.
