In a device for sampling a liquid, including a sample container (10), a pump (12) and to the sample container (10), connected inlet means (22), first valve means (28) is provided at the inlet means (22). Prior to sampling the sample container (10) is isolated from the inlet means (22) in that the first valve means (28) is closed. The pump (12) thereupon creates a vacuum in the isolated sample container (10) and after that the first valve means (28) establishes connection between the inlet means (22) and the sample container (10) in order to momentary introduce a certain amount of the liquid to the sample container (10) through the inlet means (22) by means of the created vacuum. According to the invention the vacuum is built up to a sufficient degree for achieving such momentary sucking up of the liquid that its homogeneity does not have time to appreciatly change during the course of the sucking up. The invention relates to a method and a device. |
