1. A device for isolating fixed or live cells on a filter or extracting genetic material from live cells, comprising:

  • a compartment with an interior volume for receiving liquid carrying said cells, a lower opening and an air inlet;

    a filter forming a single unit, at least provisionally, with said compartment opening, designed to retain said cells when liquid is passed through the filter;

    a needle forming a single impermeable unit, at least temporarily, with said compartment opening, the filter being positioned between the needle and the interior volume of the compartment, said needle being designed to pierce a plug of a vacuum tube with negative pressure relative to ambient pressure in order to aspirate the liquid through said filter; and

    a connection means between the compartment and a protective cylinder surrounding the needle, said connection means being adapted to surround, at least in part, the vacuum tube during aspiration of the liquid through the filter.
