A method for filling sample carriers with chemical and/or biological liquids can be performed by means of a liquid dispensing device. The liquid dispensing device comprises a liquid chamber. The liquid chamber is acted on by a piezo actors. Through an activating pulse generated by the piezo actor, liquid droplets are discharged from a discharge opening towards a sample carriers. In this manner, deepened portions are filled. To avoid an occurrence of wetting in the region of the discharge opening, a prepulse is generated prior to the generating of the activating pulses and a damping pulse is generated upon completion of the filling process.
