1. An apparatus for detecting cells or particles in a fluid container, comprising:
a dispenser configured to dispense at least one cell or at least one particle into a defined sub-volume of a fluid with which the fluid container is at least partially filled; and
a detection apparatus arranged relative to the fluid container and focused on the defined sub-volume directly underneath a surface of the fluid with which the fluid container is at least partially filled, the detection apparatus configured to, in a time-coordinated manner with dispensing the at least one cell or the at least one particle by the dispenser, perform a detection in the defined sub-volume and/or in one or several sub-volumes underneath the defined sub-volume in order to sense the at least one cell or the at least one particle when entering the fluid or no later than 10 seconds after entering the fluid.
