The invention relates to a drainage device for a filter unit for microbiological testing of liquids, said drainage device including a mechanical support ( 10 ), which is adapted to receive a filter unit ( 16 ), and an suction pump ( 22 ) connected to said mechanical support to aspirate a liquid substance contained in said filter unit. The device comprises: a weight sensor ( 18 ) on which said mechanical support is mounted; a user interface ( 26 ) for entering data relating to drainage and/or said liquid substance; and a control unit ( 24 ) connected to said suction pump ( 22 ), the weight sensor ( 18 ) and said user interface ( 26 ), said control unit ( 24 ) being adapted to determine, from said data, at least a first weight corresponding to a first representative signal; and, when said weight sensor ( 18 ) supplies a signal corresponding to said first signal, said control unit ( 24 ) starts operation of said suction pump ( 22 ) so as to aspirate said liquid substance contained in said filter unit ( 16 ).
