Abstract: A pipette includes an end section, a first section, a second section and a third section aligned along a central axis of the pipette tip. The end section comprises an orifice for aspirating and dispensing a fluid. A first kink is formed in an inner surface of the pipette tip between the first section and the second section, such that an angle between the inner surface of the first section and the central axis is smaller than an angle between the inner surface of the second section and the central axis. A second kink is formed in the inner surface of the pipette tip between the second section and the third section, such that the angle between the inner surface of the second section and the central axis is smaller than an angle between the inner surface of the third section and the central axis.

Abstract: A pipette tip extension attachable to a pipette tip having a proximal end, a distal end, and an exterior wall extending between the proximal end and the distal end is disclosed. The exterior wall has an outer side and an inner side and forms at the proximal end a reception aperture for inserting a pipette tip, and at the distal end a dispense aperture. The pipette tip extension further has an inner cavity, a distance element connected to the inner side of the exterior wall, and a constriction element.

Abstract: Pipetting device for pipetting a liquid driven by a gaseous working medium, the pipetting device having at least one pipette connector adapted to attach a pipette at a connection opening at least one pressurizing and/or suctioning pressure source, a gas flow connection between said connection opening and at least one pressure source, a flow restriction defining at least a section of said gas flow connection, a first sensor configured to measure a quantity indicative of the temperature of the flow restriction. The invention is further directed to a gas flow connection element for a pipetting device and to a method of pipetting a liquid volume.
