DEVICE AND ASSEMBLY FOR MICROBIOLOGICAL TESTING AND METHOD FOR THE SAME MICROBIOLOGICAL TESTING

摘要

PROBLEM TO BE SOLVED: To provide a device and an assembly for microbiological testing of a sample of liquid and a method for the microbiological testing.;SOLUTION: The device includes an envelope (11) and a filter membrane (3), and the envelope (11) includes a removable body (6) and means (4 and 5) for supporting the membrane (3) in the wetted state and the supporting means (4 and 5) include a sponge (5) and the removable body (6) includes a flexible wall (6) adapted to move toward the membrane (3), 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.;COPYRIGHT: (C)2008,JPO&INPIT
