The invention relates to a device and a method for extracting liquid samples from containers (1) and/or tubes filled with a medium (2), especially from fermenters, via a filter membrane (5) by means of a partial vacuum. Said filter membrane (5) arranged inside a sample probe (3) consists of a material acting as a sterile boundary, a supply line (6) which can be used to guide gas and a discharge line (7) which can be used to guide the sample being arranged on the sterile boundary side (5a) of the filter membrane (5).
L'invention concerne un dispositif et un procédé de prélèvement d'échantillons liquides dans des récipients (1) et/ou de tuyaux remplis d'un milieu (2), en particulier des fermenteurs, par l'intermédiaire d'une membrane filtrante (5) au moyen de vide partiel. Ladite membrane filtrante (5) disposée à l'intérieur d'une sonde d'échantillon (3) est constituée d'une matière agissant comme une frontière stérile, une conduite d'alimentation (6) conductrice de gaz et une conduite d'évacuation (7) conductrice d'échantillons étant disposées sur la frontière stérile (5a) de la membrane filtrante (5).
