Abstract
An apparatus for the microbiological testing of pressurized liquids is disclosed which includes a completely closed container, at the base of which a membrane filter is sealed. Fitted upstream from the membrane is a built-in reading window and included downstream from the membrane, is a flange comprising a lip seal and a female threaded part. The apparatus may be used in conjunction with a microbiological testing process by screwing to the container a filtration support, taking and filtering the sample to be analyzed, and then substituting for the support an incubation cartridge for the subsequent development, in an incubator, of the colonies collected on the membrane.
