ELECTRONIC PIPETTE WITH A DISPLAY AND A SELECTOR FOR CONTROLLING ASPIRATION AND DISPENSATION

摘要

A system controls aspiration and dispensation of a liquid in a pipette. The system includes a computing device and the pipette. The computing device includes a pipetting module and a first communication interface. The pipetti ng module defines an operation to perform at the pipette. The first communicati on interface sends electronic signals to the pipette, the electronic signals defining the operation to perform at the pipette. The pipette includes a sampling tube, a piston assembly, a piston drive mechanism, a second communication interface, and a microprocessor. The piston assembly mounts to the sampling tube and includes a piston rod that fits within the sampling tube. The piston drive mechanism includes a control rod having a surface tha t contacts the piston assembly. The piston drive mechanism moves the piston ro d of the piston assembly within the sampling tube thereby causing regulation o f a liquid in the sampling tube. The second communication interface receives t he electronic signals from the computing device. The microprocessor controls th e piston drive mechanism and performs the operation defined by the electronic signals.
