Abstract: The system for microbiological analysis of a support comprises a plurality of spraying devices (7), a reader (49) of an item of identification (74) of a device, an actuator (47) of that device comprising a moveable unit (61) and a drive motor of said moveable unit (61), a control unit connected to the actuator (47) and to the reader (49) which control unit is adapted to command said actuator (47) in order to move the moveable unit (61) towards the device (7) at a predetermined speed and to record a parameter representing the position of said moveable unit (61) in a memory (171) when the force exerted by the motor exceeds a predetermined threshold then to command the motor (64) in order to move said moveable unit (61) away from the device (7).

Abstract: The microbiological analysis system comprises a support (6) adapted to retain microorganisms in the neighborhood of a planar surface (24), said support (6) belonging to a predetermined type with which is associated a specific arrangement criterion, and an analysis machine comprising a magnetron, a microwave cavity (100) linked to said magnetron provided to operate in resonant mode, a receptacle (30) for receiving said support (6), an obstacle (137) for tuning the resonant mode of the cavity (100) entering partially into said cavity (100), said obstacle (137) occupying a predetermined position depending on said predetermined type, means for recognizing said specific arrangement criterion, and a control unit connected to said magnetron and to said recognizing means and adapted to verify for said support (6) whether the specific arrangement criterion is met and to refuse to launch an analysis cycle otherwise.

Abstract: 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).
