Abstract
A method and an apparatus for filling at least one liquid into at least one cavity. The method comprises filling a predetermined filling volume of the at least one liquid into the at least one cavity and determining if the liquid in the at least one cavity reaches a first liquid level in the at least one cavity. Filling the predetermined filling volume of the at least one liquid and the determining if the first level has not been reached, is repeated until enough volume of the at least one liquid has been added to the cavity or if the first level has been reached. The predetermined filling volume is equal to or smaller than a buffer volume above the first liquid level in the at least one cavity.
Claims5
A method for filling at least one liquid into at least one cavity, the method comprising:
- inserting a dispensing needle into the at least one cavity to a position at which a liquid level detector is at a lower level of a buffer volume;
- detecting with the liquid level detector whether a first liquid level in the at least one cavity is reached;
- filling a pre-determined filling volume of the at least one liquid into the at least one cavity if the first liquid level is not reached;
- determining if the at least one liquid in the at least one cavity reaches the first liquid level in the at least one cavity;
- and
- repeating the steps of filling the pre-determined filling volume of the at least one liquid and the determining, if the first liquid level has not been reached;
- wherein the pre-determined filling volume is equal to or smaller than the buffer volume at whose lower level the liquid level detector is positioned above the first liquid level in the at least one cavity.
