  • Patent number: 11918995
    Abstract: An automatic liquid transfer optimization pipetting apparatus and method is disclosed. Namely, a liquid handling apparatus includes a pump supplying a nozzle (i.e., a pipette tip) via a conduit, one or more pressure sensors, and an electronic controller, and wherein the pipette tip is submerged in a liquid. Further, a method of automatic liquid transfer optimization pipetting includes the steps of actuating the pump to move a designated volume of liquid and then allowing the system to settle to a steady state after completion of pump actuation.

  • Publication number: 20240033725
    Abstract: A method for automatically maintaining a pipette tip depth in a conductive fluid during a fluid transfer operation, comprising the steps of: providing a pipetting device, comprising: a pipette tip; a first and a second electrode on the outer surface of the pipette tip; a frame supporting an actuator that is operatively connected to the pipette tip; and a controller that is in electrical connection with the first and second electrodes; providing a container fixed in height relative to the frame, the container holding a conductive fluid having a first liquid level; positioning the pipette tip in the container such that at least a portion of the first and second electrodes are submerged in the conductive fluid; measuring by the first and second electrodes a change in resistance relative to the conductive fluid; sending by the first and second electrodes a signal to the controller relative to the change.

  • Patent number: 11819840
    Abstract: A pipette tip for and method of automatically maintaining pipette tip depth in a fluid during a fluid transfer operation is disclosed. The pipette tip includes, for example, two electrodes that run substantially the full length of the pipette tip for measuring the resistance therebetween when submerged in a conductive fluid. A method is provided of automatically maintaining the depth of the pipette tip in a liquid throughout a pipetting operation, as the liquid surface rises or falls in its container, without any prior knowledge of the container geometry.
