The invention relates to a device and a method for taking liquid or gaseous samples from containers and/or tubes that are filled with a medium, in particular from fermenters, by means of negative pressure, wherein an element which acts as a non-return valve is arranged within a sample probe as an inlet for the sample that is to be taken, and a supply line which is able to convey gas and a discharge line which is able to discharge sample are arranged on a common side of the element.
L'invention concerne un dispositif et un procédé de prélèvement d'échantillons liquides ou gazeux de contenants (1) remplis d'un agent (2) et/ou de tuyaux, notamment de fermenteurs, par une dépression. Une sonde (3), destinée au prélèvement d'échantillons, abrite un élément (5) agissant comme valve de retour comme entrée pour l'échantillon à prélever. Une conduite d'alimentation (6) transportant du gaz et une conduite d'évacuation (7) évacuant les échantillons sont placés du même côté de l'élément (5).
