The present invention provides an apparatus for selecting motile biological species, in particular sperm, comprising a first chamber for receiving a medium containing the species to be selected and, separate therefrom, a second chamber for receiving the selected species in a further medium, and characterized in that it comprises a bridge element mountable on the chambers and having at least one flat channel formed by limiting walls which, when the bridge element is mounted, extends from the first chamber to the second chamber, has an opening in the area of the first chamber and the second chamber in each case, and is fillable with a medium in which the motile biological species can move, such that the medium in the first chamber is connected with that in the second chamber. |
