摘要：
A sample preparation unit for sterility tests, comprising: a housing body (2) that includes at least two ports (4,5,6) adapted to serve as a fluid inlet and / or outlet, a membrane holder (10) and a cover part (3) provided so that a membrane chamber (12, 12a, 12b) adjacent to said membrane support (10) is defined； wherein one of said at least two ports (4,5,6) is installed so that it allows a fluid transfer to / from a first volume of said membrane chamber (12,12a, 12b) in a position upstream of a membrane (8) to be placed on said support (10), and the other of said ports (4,5,6) is arranged to admit the transfer of fluid to / from a second volume of said membrane chamber (12,12a , 12b) in a running position under a membrane (8) to be placed on said support (10)； and a mobile part (7) provided in said housing body (2) so that both are mobile, relative to each other, thus selectively interrupting / establishing fluid transfer between at least one of the at least two ports (4, 5.6) and said membrane chamber (12)； characterized in that the movable part (7) is in the form of a rotating ring member about at least part of the periphery of the housing body (2).Una unidad de preparación de muestras para pruebas de esterilidad, que comprende: un cuerpo de alojamiento (2) que incluye al menos dos puertos (4,5,6) adaptados para servir como entrada y/o salida de fluido, un soporte de membrana (10) y una parte de tapa (3) provistos de manera que se define una cámara de membrana (12, 12a,12b) adyacente a dicho soporte de membrana (10)； donde uno de dichos al menos dos puertos (4,5,6) está instalado de manera que admite una transferencia de fluido a/de un primer volumen de dicha cámara de membrana (12,12a,12b) en una posición corriente arriba de una membrana (8) que debe colocarse sobre dicho soporte (10), y el otro de dichos puertos (4,5,6) está dispuesto para admitir la transferencia de fluido a/de un segundo volumen de dicha cámara de membrana (12,12a,12b) en una posición corri
