Abstract: An in-vitro diagnostic device including a pipetting unit and a pipetting method, which allow for a more reproducible and more precise pipetting of liquids, when piercing through a lid of a closed liquid container is required. The pipetting unit is controlled to repeat penetration of the lid of the closed liquid container if the pressure difference between the interior of the liquid container and the surrounding is outside an allowable predefined pressure range.
