Abstract
The invention relates to a process and a device for calibrating a sampling and metering pipette and a pipette adapted to be used in the process with the device. The volume of the sampling chamber of the pipette is adjusted to zero by means of a knurled button (3) and an adjusting screw (7) is actuated to set the stroke of a plunger for taking a sample at a zero value. The volume of the sample chamber is adjusted by means of the knurled button (3) to determine a mean value of the sample volume, and a new adjustment of the brake screw (7) is made to a value corresponding to the difference between a displayed volume value and the mean value of the sample volume.
