The device for microbiological testing of a sample of liquid includes an envelope and a filter membrane, the envelope including a removable body and a support for the membrane in the wetted state; the support including a sponge and the removable body including a flexible wall adapted to move toward the membrane, when the device is subjected to a reduced pressure and to return to its initial position when the 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 the sample between the inlet aperture and the outlet aperture of the device, of subjecting the device to a reduced pressure, of making the reduced pressure cease, and then of detecting the presence of microorganisms on the membrane of the device.
