Abstract (en)
[origin: EP1439002A2] A dosing apparatus (1), to deliver doses of a fluid in a laboratory, has a manual press button (3) on a spring (9), with a sensor (12) to register the pressure on it. The sensor is linked to the electrical control (17) for an electric drive motor (14), for its operation according to the applied manual pressure. A voltage supply (18) gives the required power from a battery and the like. A plunger (5,6) is operated by the motor to force out the dosed fluid.
