Abstract: The invention relates to a pipetting device having tube with an opening at one end for suctioning or discharging a sample fluid, and can be operatively connected to a pressure generation device at the other end. A first electrode is formed on the pipetting device that forms a measuring capacitor together with a second electrode formed by at least one part of the sample fluid and that can be received in the tube and the measuring capacitor is operatively connected to a measuring unit, and the measuring unit is designed to determine a volume of the suctioned or discharged sample fluid according to the capacity of the measuring capacitor. The invention also relates to a fluid processing system having a pipetting device of this type, as well as a method for determining a processed fluid volume during pipetting with a pipetting device of this type.

Abstract: Aspiration of a pipette arrangement is initiated. A sensor arrangement senses a least one prevailing first parameter that is dependent from the effect in the pipette arrangement during initiating and upholding the suctioning action. This at least one parameter is analyzed in an analyzing stage. From a result of this analysis and in a determining stage at least one test criterium TC for at least one further parameter as sensed by the sensor arrangement is determined. In a checking stage there is checked whether this further parameter fulfills the at least one test criterium.

Abstract: Digital microfluidics system manipulates samples in liquid droplets within disposable cartridges that have bottom layer, top layer, and gap between the bottom and top layers. The system has a base unit with cartridge accommodation sites and a central control unit for controlling selection of individual electrodes of electrode arrays and for providing these electrodes with individual voltage pulses for manipulating liquid droplets within the cartridges by electrowetting. The system further has board accommodation sites located at the cartridge accommodation sites that each can take up a swappable electrode board having an electrode array and electrical board contact elements individually connected to electrodes of the electrode array. Each board accommodation site has electrical base unit contact elements that are connected to the central control unit and that are configured to engage with the electrical board contact elements of a swappable electrode board that is placed at the board accommodation site.

Abstract: The invention relates to a pipetting device having an exchangeable pipette tip for suctioning and discharging fluid volumes for use in automated laboratory systems. The invention relates to a pipetting device having a pipette tip detection unit and for detecting a pipette tip on a pipette device of this type. A detection unit detects whether a pipette tip is connected to the pipette tube or determines a characteristic feature of the connected pipette tip. The pipette tip forms at least one portion of a first electrode when the pipette tip is in electrical operative contact with the pipette tube and, e.g., a pipette tip holder, a contact for setting down the pipette tip holder or a working table over which the pipette tube can be moved forms at least one portion of a second electrode.

Abstract: A device which has a deliverable sensor, a container for receiving a liquid, a container environment and a signal processing circuit, the input side of which can be connected circuitry-wise to the sensor. The device is designed to perform a capacitive liquid level measurement in normal operation using the sensor, wherein a threshold value can be predefined for the signal processing circuit for normal operation. The device has a classification module which can be connected with an input side or line connection circuitry-wise to the sensor, is designed to make a capacitive measurement of the liquid in the container using the sensor and can be connected circuitry-wise to the signal processing circuit in order to trigger the specification of a threshold value using the sensor for capacitive measurement of the liquid.

Abstract: A transport tool for transporting a laboratory article using a pipette of a pipetting system, and having a plug-in sleeve at a top end, an article holder at a bottom end, and a connecting part which connects the plug-in sleeve to the article holder. The plug-in sleeve has a side sleeve wall and a bottom which surround an interior space of the plug-in sleeve having a cylindrical or conically tapering shape. The plug-in sleeve further has an upward-facing opening for receiving an end of a pipette of an automated pipetting system. The article holder has a holding element oriented downward away from the connecting part. The holding element having at least two elongated projections which has one or more snap hooks protruding outwards to hook under a storage opening of a pipette tip carrier.

Abstract: A disposable cartridge configured as a digital microfluidics system for manipulating samples in liquid portions having a cartridge accommodation site and a central control unit for controlling selection of individual electrodes of an electrode array located at the site and for providing plural electrodes with individual voltage pulses for manipulating liquid portions by electrowetting. The cartridge has a hydrophobic working surface and a rigid cover with a second hydrophobic surface, the hydrophobic surfaces facing each other and being separated in parallel planes by a gap. The cartridge has plural pipetting guides for safe entering/withdrawing liquids into/from the gap with a pipette tip. At least one of the pipetting guides provides an abutting surface sealingly admittable by a counter surface of a pipette tip, located at a pipetting orifice that reaches through the rigid cover, and configured to prevent a pipette tip from touching the hydrophobic working surface.
