    摘要： Liquid dispensing devices are provided. Aspects of the devices include an actuator comprising a movable shaft; an elongated body, e.g., a cylinder, comprising a central channel, a proximal end and a distal end, wherein the distal end comprises an orifice; and a plunger comprising a proximal end and a distal end, wherein: the proximal end is mechanically coupled to the movable shaft, and at least a portion of the distal end of the plunger is moveably positioned within the central channel. Also provided are systems that incorporate the liquid handling device, which may be present as an array of liquid handling devices, as well as methods of using the devices and systems, e.g., in liquid dispensing applications.

    摘要： A pipette device comprises a pipette channel filled with compressible working gas, a pipette piston movable along the pipette path, a piston drive, which drives the pipette piston, a control device, a data memory connected to the control device for signal transmission, a pressure sensor which detects the pressure of the working gas and which is connected to the control device, a position sensor which detects a position of the pipette piston and which is connected to the control device. The control device is designed to determine a quality of a dispensing sequence on the basis of a target residual quantity value, which represents the target residual quantity of dosing liquid remaining in the pipette channel, of a working gas pressure and of an end position of the pipette piston, in each case after the end of the dispensing sequence, and to output the determined quality.

    摘要： The invention relates to a pipetting device for receiving and dispensing fluid volumes. The pipetting device has a drive device with an electric motor and a gear device with a first output device. The gear device is driven by the electric motor by means of a rotary motion and is designed to transmit a rotary motion of the electric motor to the first output device. According to the invention, the gear device has a second output device and is designed to transmit a rotary motion of the electric motor to the second output device.

    摘要： A pipette is described which includes a piston for aspirating liquid into and dispensing out of a container in the pipette. The pipette is provided with at least one tracking element which is able to count the magnitude of some variable or variables relating to the amount of use of the pipette, at least one operating device for creating a limit magnitude for each variable, and for giving information when the limit value is exceeded. Thus, the user may, for instance, be warned when he may be exposed to high workload stress possibly causing injuries.
