The device for microbiological testing of a sample of liquid includes an envelope ( 11 ) and a filter membrane ( 3 ), said envelope ( 11 ) including a removable body ( 6 ) and means ( 4, 5 ) for supporting said membrane ( 3 ) in the wetted state; said supporting means ( 4, 5 ) including a sponge ( 5 ) and said removable body including a flexible wall ( 6 ) adapted to move toward said membrane ( 3 ), when said device is subjected to a reduced pressure and to return to its initial position when said reduced pressure ceases. The assembly includes a device of the above kind and a clamp adapted to grip the device in the manner of a vise. The method includes the step of obtaining such a device, of passing said sample between the inlet aperture and the outlet aperture of said device, of subjecting said device to a reduced pressure, of making said reduced pressure cease, and then of detecting the presence of microorganisms on the membrane of said device.
