The invention relates to a hand-held pipetting device () with a housing () and a pipette receptacle () on the housing () for a replaceable pipette (). The pipette () is received with its first end in the pipette receptacle () and has a tip () as a second end. Furthermore, the hand-held pipetting device () has a negative pressure source for aspirating a liquid, an overpressure source for dispensing an aspirated liquid, and an air line which connects the negative pressure source and overpressure source with the pipette receptacle. A valve system, which is at least partially electrically controllable, is arranged within the air line and is controlled by an aspirating button () provided on the housing and by an dispensing button (). A light source () is provided on the housing () at a short distance to the longitudinal axis () of the pipette receptacle (). On the light source, an optical system is provided which generates a light cone () from the light beams going out of the light source.
