Estimating the term…
The unit comprises a filter membrane filter module and a collection module for liquid coming from the filter module, with the filter module comprising an inlet compartment as well as an evacuation compartment for the liquids, the filter and collection modules being rotatably mounted relative to each other. The method comprises the step of obtaining such a unit, of disposing the filter and collection modules in a first position, of passing a liquid from the filter module to attain the collection module, of disposing the filter and collection modules relative to each other in a second position, and the step of passing another liquid from the filter module to attain the collection module.
A unit for preparing a sample for the microbiological analysis of a predetermined volume of liquid that may contain microorganisms, said unit comprising a filter module and a collection module for receiving liquid coming from said filter module, with said filter module comprising an inlet compartment for inletting said predetermined volume by an inlet opening of said filter module, said inlet compartment being adapted to contain the whole of said predetermined volume, as well as an evacuation compartment for evacuating said predetermined volume by an evacuation opening of said filter module to said collection module, said evacuation compartment being separated from said inlet compartment by a filter membrane, the filter and collection modules being rotatably mounted relative to each other, and having, relative to each other, a first relative predetermined position, in which said evacuation opening of said filter module is in register with a first opening of said collection module and a second relative predetermined position different from said first position, in which said evacuation opening of said filter module is in register with a second opening of said collection module characterized in that said inlet and evacuation compartments are on opposite sides from each other relative to said filter membrane with said inlet compartment being arranged such that, when said predetermined volume is in said inlet compartment the liquid is in contact with the filter membrane over at least the majority of its surface;
