1. be used for comprising from the device of liquid sample concentrate microbial:

  • -filter body comprisesThe liquid inlet, described liquid sample can enter described filter body by described liquid inlet, and described liquid inlet is suitable for engaging with described liquid sample,Liquid exit, described liquid sample can leave described filter body by described liquid exit, and described liquid exit is suitable for and the low-pressure chamber sealing engagement, andThe sorbing material bed of fluid permeable, it is installed between the described liquid inlet and described liquid exit in the described filter body, and can adsorb microorganism by electrostatic interaction, thus, exert pressure when poor when crossing over described filter body, described liquid sample is inhaled in the described filter body by described liquid inlet, and passes the sorbing material bed of described fluid permeable before leaving by described liquid exit;

    -low-pressure chamber, it has the liquid inlet that is suitable for the liquid exit sealing engagement of described filter body, is used for from described low-pressure chamber deflated air but also have;

    And-vacuum pump, it is suitable for the air sealing engagement with described low-pressure chamber.
