In the method of dispensing liquid according to the invention, when liquid is aspired by the pump to the pipette, the required size of dose of the liquid is dispensed from the pipette in proportion to the atmospheric air fed thereto through a valve or a set of connected to the pipette, whereas the amount of supplied atmospheric air is processor programmed by the determination of time and/or flow rate and/or damping of the supply of atmospheric air into the pipette. Pipetting device according to the invenvention comprises a housing with a handle (3) for mounting the pipette (4), whereas in the housing, an air pump (6) is located, connected to the pipette (5), and a processor (15) to control the operation of the device. The pipetting device comprises also a set of valves (10) for processor (15) controlled atmospheric airflow during dispensing liquid, whereas the set of valves (10) is connected to the pipette (5).
The method of dispensing liquid in a pipetting device comprising a housing with a holder to mount a pipette, whereas an air pump connected to the pipette, and a processor controlling the device operation is disposed in the housing, wherein after aspiration by the pump of liquid into the pipette, the required size of the liquid dose is dispensed form the pipette in proportion to the amount of atmospheric air supplied thereto through a valve or a set of valves connected to the pipette, characterized by that the amount of the supplied atmospheric air is programmed in the processor by determination of time and/or flow rate and/or damping of the supply of atmospheric air to the pipette.
The pipetting device comprising a housing with a pipette mounting holder, whereas an air pump connected to the pipette is disposed in the housing, characterized by that it includes at least one valve for controlled atmospheric air flow during liquid dispensing, whereas this valve is connected to the pipette (5).
