Abstract

An apparatus for the measurement of the surface tension of liquids by means of a capillary tube for supplying gas, the tube having a connector and a nozzle, may be used in a measuring device. In order to create an apparatus that is easy to manufacture and handle, and that can be used reliably in a variety of liquids, the capillary tube is arranged, at least partially, in a crucible for receiving the liquid and is mounted on the wall of the crucible, whereby the connector is arranged outside the interior of the crucible. The connector is connected to the gas line of the measuring device and to a pressure sensor and/or a flow meter.
