In a device for taking and measuring samples having several testing vessels containing the samples in a testing liquid, the testing liquid is supplied to the individual testing vessels from a reservoir through a first pump and first valves which are connected to each testing vessel. From the testing vessels the samples are supplied to one or more detector cells, through second valves which are connected to the testing vessels. The second valves are arranged in a row behind each other. Between the last valve of this row and/or the detector cell(s), a second pump is provided. Thus, a serial withdrawal of samples from the individual testing vessels can be carried out with only two pumps, and the contents of the testing vessels are refilled to the nominal filling level from the reservoir at the same time.
