Abstract: A sample rack that has at least one axially extended receptacle for a sample tube (30). The sample rack has a code arrangement on its outside. This code arrangement contains information regarding the position of the at least one receptacle as well as information regarding the total number of receptacles and/or the dimension of the sample rack. A sample carrier system (1) is further provided that has a sample carrier with at least one sample rack receptacle and a set of sample racks. The sample rack receptacle and the sample racks have interacting mechanisms which characterize their affiliation.

Abstract: A pipetting apparatus and method capable of detecting a liquid within an intermediate section of a pipette tube of the pipetting apparatus. The intermediate section is located between an upper section of the pipette tube at which a first electrode is arranged and a lower section at which a second electrode is arranged. The first and second electrodes form a measurement capacitor and are operationally connected to an impedance measurement unit, which is adapted to detect whether liquid, such as a portion of a sample liquid or system liquid, is present within the intermediate section based on the measured impedance or change of impedance, e.g. an increase of the capacitance and/or a decrease of the resistance, of the measurement capacitor caused by a presence of the liquid within the intermediate section.

Abstract: A pipetting apparatus having a pipette tube with a first end provided with an opening for aspirating and/or dispensing of a sample fluid and a second end operationally connected to a pressure generating means. The pipetting apparatus has at least one measuring unit adapted to determine at least one measurement value of the sample fluid based on the aspirating and/or dispensing of the sample fluid and to provide a sample fluid measurement signal representative thereof to an output of the measuring unit. The pipetting apparatus also has a control circuit operationally coupled to the output of the measuring unit and the input of the pressure generating means, the control circuit is configured to control said pressure generating device based on the sample fluid measurement signal.

Abstract: An identification device for identifying identifiers on and/or features of laboratory objects and/or of samples located therein in conjunction with automated laboratory systems or facilities, for example, medical, chemical, or pharmaceutical analysis devices. Barcodes on sample containers, for example, sample tubes, reagent tubs, or microplates are used, for example, as identifiers. An optical recording unit and a mirror are used, the spacing is variable for the detection of laboratory objects, each at different distances, from a recording distance by the optical recording unit is within a depth of field of the optical recording unit. The mirror is used for imaging the laboratory object to be detected on the optical axis. The identification device is substantially simplified, more reliable, and more cost-effective in comparison to known devices that use a zoom lens together with an autofocus unit.

Abstract: A cartridge for use in an electrowetting sample processing system, the cartridge having one or more inlet ports for introducing an input liquid into an internal gap of the cartridge, which has at least one hydrophobic surface for enabling an electrowetting induced movement of multiple microfluidic droplets separated from the input liquid. The cartridge further has at least one outlet port that is operably connected to the inlet port for providing a liquid flow through the cartridge, if a liquid driving force, in particular an electrowetting force or a pressure force, is applied to at least a part of the input liquid.

Abstract: A cartridge, in particular a disposable cartridge, for use in an electrowetting sample processing system. The cartridge has a liquid input port for introducing an input liquid into an internal gap of the cartridge, the input liquid providing for at least one droplet, directly or via a liquid separation process within the internal gap, and the internal gap having at least one hydrophobic surface, at least one processing zone for processing samples located in the processing zone, and a delivery zone for delivering the at least one droplet from the liquid input port to the at least one processing zone. The delivery zone is configured to provide a repeating pattern of interacting electrowetting force for simultaneously transporting the at least one droplet within the delivery zone.
