Abstract: The invention concerns pipette tips for connecting to a pipette tube of a pipetting device are used for taking up and discharging fluids. The pipette tip is in the shape of an elongated tube forming a pipette body that has an opening at one end and is designed for connecting to the pipette tube at the other end. The pipette tip has a first electrode as a volume measuring electrode of a measuring capacitor and a second electrode as an immersion detector electrode. The first electrode is located on an outer surface of the pipette body or is embedded in the pipette body, and the second electrode is located at least partially on an inner surface of the pipette body.

Abstract: A method for aspirating a first liquid medium of two liquid media of different density from a sample container comprises: lowering a pipette of the laboratory automation device into the sample container until a pipette tip of the pipette has passed a lowering distance from the surface of the first liquid medium in the sample container, wherein the lowering distance is chosen, such that the pipette tip passes at least an aspiration volume in the sample container; aspirating liquid from the sample container during the lowering of the pipette by generating an underpressure in the pipette, wherein the first liquid medium is aspirated, and after the interface and the pipette tip pass each other, the second liquid medium of the two liquid media is aspirated; measuring a pressure in the pipette during the lowering of the pipette and detecting a position of the interface, when a slope of the pressure changes; when the lowering distance has been passed and no interface is detected, aspirating the aspiration volume from the first liquid medium and dispensing the aspiration volume of the first liquid medium into a further sample container.

Abstract: A storage device for storing one or more pipettor consumables contains a storage plate having an upper side and a lower side, and, on the upper side, a number of accommodation seats arranged in an array. Each accommodation seat is configured to receive a pipettor consumable in an upside-down orientation. The storage device has one or more positioning elements for positioning the storage device in relation to a carrier, and/or one or more stacking elements for stacking the storage device with another storage device.
