Holding apparatus for holding a pipetting container at a pipetting device

Holding apparatus (5;

• 50;
• 50′;
• 100) for holding a pipetting container (9;
• 9′), at a pipetting apparatus (1), comprising
• a tubular connecting section (51;
• 51′;
• 101), that is configured to hold a tubular end (9d) of the pipetting container (9;
• 9′) in a pipetting position with a clamping connection, the pipetting position allowing pipetting of a liquid into the pipetting container by means of the pipetting apparatus,
• a clamping connection device (102;
• 103), which is arranged at the connecting section and which comprises a spring device (102) for the establishment of the clamping connection, and an air chamber device (103) for releasing the clamping connection,
• wherein the spring device (102) is configured to exert a spring force (F), by way of which the tubular end of the pipetting container is held at the connecting section in the pipetting position, wherein the spring device (102) comprises a spring element, which effectuates said spring force and which is arranged in an air chamber of the air chamber device,
• and the air chamber device (103) is configured to be deformed in the pipetting position by a partial vacuum applied to the air chamber, thereby the spring device being elastically deformed such that the clamping connection being released.
