Abstract
The invention relates to a method of separating biological particles from the liquid containing same for purification, analysis and optionally diagnostic purposes. The inventive method comprises at least one step involving vertical filtration through a filter having a porosity that is adapted to the type of biological particles to be separated, such that said particles are retained by the filter. The invention is characterized in that: (i) the method involves the use of a filter comprising at least one basic filtration zone, whereby each basic filtration zone has a limited surface area; and (ii) the surface area of each basic filtration zone and the number of basic filtration zones are selected as a function of the type of liquid to be filtered, the type of biological particles to be separated and the volume of liquid to be filtered.
