The invention relates to a device (1) and a method for determining the action of active ingredients on nematodes and other organisms in aqueous tests. The device (1) according to the invention comprises a holder (13) for a cell culture plate (30) having multiple wells (31) in which the nematodes can be filled with the active ingredients, said cell culture plate (30) having a bottom side (33), a top side (32) and also side walls extending between bottom side (33) and top side (32), a camera (11) which is used to record images of preferably the bottom side (33) of the cell culture plate (30), a lighting mechanism (14) having at least a first light source (15) which illuminates the cell culture plate (30), there being arranged between the first light source (15) and a first side wall (34) of the cell culture plate (30) in the installed state a first optical unit which directs the light of the first light source (15) through the first side wall (34) in the direction of the bottom side (33) of the cell culture plate (30). The method according to the invention makes it possible to simultaneously investigate many active ingredients within a very short time.
