Abstract

The invention relates to a pipetting device, more particularly a pipette or repeater pipette, for pipetting fluid laboratory samples, comprising: an electric control apparatus, by means of which a pipetting process is electrically controllable, a movable part, by means of the movement of which the fluid sample is pipettable, an electrically actuatable motor apparatus, by means of which the movement of the movable part is driveable depending on at least one first speed value defining the speed of the movable part, a measuring apparatus, by means of which at least one measured value which is influenced by the drag caused when pipetting the fluid sample is measurable, wherein the electric control apparatus is configured for the purposes of the at least one first speed value being fixable by the electric control apparatus, depending on at least one measured value. The invention furthermore relates to a method for operating the pipetting device.
