Abstract: A pipette with an adjustable dosing increment, wherein a control apparatus determines a dosing volume by a set dosing increment when a syringe is inserted in the pipette, and determines a maximum possible number of dosing steps following an execution of a reverse stroke without refilling the syringe given the set dosing increment and completely or partially filled syringe by the position of a displacement means on the path, and displays the maximum number of dosing steps on a display apparatus until the reverse stroke is executed. The control apparatus also determines the number of executed dosing steps and displays the number of executed dosing steps and/or the number of dosing steps still possible without refilling the syringe on the display apparatus.
