System, method, and computer program product for synchronizing a system for
aspirating and/or dispensing of liquid samples that includes a microejection device
and a pump, which are connected with one another via tubing, wherein a computer
is capable of being loaded with an activatable computer program product for synchronizing
operation of the microejection device and the pump. Embodiments are characterized
in that the loaded and activated computer program product, directs the computer
to control and synchronize the system: (a) to actively define a sample volume and
dispense the defined sample volume using the microejection device, which is filled
with sample liquid; and (b) to track a part of the pump that conveys liquid around
a value, dependent on the sample volume, which is defined and is actively dispensed
only by the microejection device, to prevent excessive pressure differences in
the microejection device, tubing, and pump.
