ABSTRACT:
Method and apparatus for the microbiological testing of liquids to identify and count living microorganisms contained therein includes a tubular sleeve for collecting the liquid sample to which there is attached at one end a microporous membrane filter. Each end of the sleeve has the shape of a female receptacle portion where into one end a container housing a culture medium can be nested by force for applying the medium to the underside of the filter and where into the other end a cover can be nested to provide a substantially tight sealing of the device. Preferably, the tubular sleeve is in the form of a bellows the convolutions of which can be either compressed or expanded to correspondingly alter the volume of the sleeve between minimum and maximum values.
