Described are exemplary embodiments of a handheld, powered positive displacement pipette assembly, including a plurality of syringes of different volumes and a powered positive displacement pipette having unique mechanisms for the retention, identification, operation, and ejection of said syringes.

Powered positive displacement pipette assembly

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.

Positive displacement pipette syringe identification system

Pipette syringe

Described are exemplary methods for dispensing liquid from a handheld, powered positive displacement pipette.

Powered positive displacement dispensing methods

Described are exemplary embodiments of a handheld, powered positive displacement pipette having unique mechanisms for the retention, identification and ejection of associated pipette syringes.

Powered positive displacement pipette

Described are exemplary embodiments of a grasping mechanism for a powered, handheld positive displacement pipette, the grasping mechanism configured to grasp and releasably retain the piston head of a syringe that is usable with the pipette.

Powered positive displacement pipette syringe piston grasping mechanism

Described are exemplary embodiments of a syringe for use with a handheld positive displacement pipette, the syringe being releasably retainable by the pipette. Syringe embodiments may be configured to hold different material volumes. At least certain syringe embodiments may include a cooperative adapter that is used to releasably couple the syringe to the pipette.

Syringe for powered positive displacement pipette

Described are exemplary embodiments of a handheld, powered positive displacement pipette assembly, including a plurality of syringes of different volumes and a powered positive displacement pipette having unique mechanisms for the retention, identification and ejection of said syringes.
