The electronic device (1) for dosing fluids, comprises an elongated housing (2), a displacement device arranged in the housing or arranged with a displacement element, a retaining device (14) at the bottom end of the housing to retain a pipette tip or a syringe, an electrical operating device in or on the housing, a drive (7) with an electric motor (8) arranged in the housing, an electrical information device in or on the housing, an electrical controlling device arranged in the housing, and an electrical power supply. The electronic device (1) for dosing fluids, comprises an elongated housing (2), a displacement device arranged in the housing or arranged with a displacement element, a retaining device (14) at the bottom end of the housing to retain a pipette tip or a syringe, an electrical operating device in or on the housing, a drive (7) with an electric motor (8) arranged in the housing, an electrical information device in or on the housing, an electrical controlling device arranged in the housing, and an electrical power supply. The electrical controlling device is connected with the electric motor, the electrical operating device and the electrical information device. The displacement device has a cylinder with a piston longitudinally and displaceably arranged in the displacement device. The information device comprises an electro-optical unit, a display device and electrical light sources, which are arranged in the longitudinal direction of the housing one after the other. The dosage device has a long container shaft on the upper side, an angular container head, the electrical operator control and/or the electrical display device on the container head. The electro-optical device is arrow-shaped and arranged in the longitudinal direction of the container. The two arrow-shaped electro-optical devices are positioned away from each other. The electrical information device is arranged on the lower end of the container. The dosage device has an electro-optical display device, which has an externally observable display upper surface. The electrical information device is arranged on the outer side of the housing, on which the electrical operator control and/or the electrical display device is arranged. The dosage device has an electrical mode key and an electrical parameter key for altering between different menus. The control device controls the display of the respective functions of the mode key and/or the parameter key and/or the control keys by the display device. One of the two electrical control keys has a second switching point. The electrical control device controls an over-blowing hub through the displacement element by reaching the second switching point. The mode key and the parameter key are arranged near to each other and/or the control keys are arranged between the mode key and the parameter key. A closing key is arranged under the mode key and/or the parameter key and/or the control keys. The mode key, the parameter key and the control keys are arranged on the upper side of a connection area between the elongated container shaft and the container head. The closing key is arranged in the connection area between the container shaft and the container head. The control key is arranged on the retaining device and has the second switching point for triggering the over blowing hub. |
