Described is a device for collecting micro-organisms, in particular legionella bacteria, from a liquid in a filter, with a bottle (1) with balloon holder (3) and, at least during use, balloon (4); a filter holder suitable for placing at least during use on the balloon holder (3) with a filter (8), the pore size of which is such that the micro-organisms are stopped; and a cover (19) fitting onto the bottle for clamping the filter holder on the balloon (4) during operation, comprising an outlet for the liquid (21 ), a connection point (20) for gas supply, such as via a gas cartridge, and a pressure-relief valve (14). When such a device is applied water samples can be taken in safe manner, the filter holder can be sent unopened to a laboratory where the quantity of legionella bacteria can be determined, particularly using DNA analysis. |
