  • Patent number: 11911767
    Abstract: Described are exemplary embodiments of a syringe identification system for use with a positive displacement pipette, such as a handheld powered positive displacement pipette. An exemplary syringe identification system may include a sensor, such as a color sensor, that is located at or near a distal end of the pipette and arranged such that the sensor is operative to read an identifying marking(s) on a syringe that has been installed to the pipette. The sensor may be a color sensor having an illumination source and configured to read a color code on the syringe. The color code may be usable to identify the syringe to the pipette.
