ABSTRACT:
A liquid dispensing and/or aspirating device to be operated manually repeatedly, having a controlling device, a motor drive, control electronics, a manually actuatable actuating element, and a programming element, where the quantity of liquid which is conveyed by motor on actuation of the actuating element is adjusted in the control electronics by the programming element. A process interval (tp) for a plurality of process steps to be carried out in succession is stored in the control electronics. A first type of actuation of the actuating element triggers an individual process step, while a second type of actuation automatically results in repeated successive triggering of process steps, each in the process interval (tp). Handling of the device in practice is greatly improved by the fact that the process interval (tp) is automatically determined by the control electronics by analyzing the interval(s) occurring between the individual actuations of the actuating element.
