  • Patent number: 10493444
    Abstract: A pipetting device (100) for an apparatus for processing a sample or reagent is disclosed. The pipetting device (100) comprises a coupling mechanism, wherein the coupling mechanism comprises at least a first coupling unit (104) adapted to be coupled to a first pipetting tip (108) and a second coupling unit (106) adapted to be coupled to a second pipetting tip (110), and a selection element (138) for selectively allowing a coupling of the first coupling unit (104) to or releasing the first coupling unit (104) from the first pipetting tip (108) and for selectively allowing a coupling of the second coupling unit to or releasing the second coupling unit (106) from the second pipetting tip (110). The selection element (138) is mechanically coupled to the first coupling unit (104) and the second coupling unit (106). Further, an apparatus (198) for processing a sample or reagent and a method for pipetting a sample or reagent are disclosed.

  • Publication number: 20100137574
    Abstract: A system and method for the automated extraction of nucleic acids from nucleic acids containing samples are disclosed. In the system, reagents provided in cavities of a reagent plate are transferred to samples accommodated in a process plate using a pipetting device comprising pipettes provided with disposable pipette tips for pipetting of the reagents to obtain sample-reagent mixtures, the sample-reagent mixtures accommodated in the process plate are incubated by an incubating device to release the nucleic acids; the released nucleic acids accommodated in the process plate are separated by a separating device and released to obtain extracted nucleic acids containing fluids; the extracted nucleic acids containing fluids are transferred to cavities of an output plate by disposable pipette tips; wherein each of the samples is assigned one-to-one to a cavity of the reagent plate, at least one of the disposable pipette tips and a cavity of the output plate.
