A method of selecting pipetting parameters of a pipetting device for dispensing or pipetting a specific volume of a liquid sample, includes a fluid column of a fluid chamber of the pipetting device set into oscillation at the beginning of the aspiration, the pressure is monitored with the pressure transducer in the fluid chamber, and the pressure changes generated during aspiration into measuring signals are recorded. These measuring signals are processed by a computer or micro-processor and reproduced as a pressure curve, which is characteristic for the fluid column with the aspirated liquid sample, and which is compared with known pressure curves. Based on this comparison, pipetting parameters of the pipetting device are selected for the dispense or for pipetting a specific volume of the liquid sample. Selectable pipetting parameters include a speed of a movement of a pump piston of the pipetting device.
