Electronic pipette for small mechanical arm

The utility model relates to an electronic pipette for a small-sized mechanical arm, which comprises a pipette body, a pipette connecting contact and a pipette electromagnetic mounting port are arranged on the side surface of the pipette body, and the pipette connecting contact is used for being matched with an electric contact on the mechanical arm to realize electrification; the pipette electromagnetic mounting port is used for being matched with an electromagnetic adsorption end on a mechanical arm; a detection sensor for detecting the liquid level is arranged at the front end of the gun body; the detection sensor is a laser radar. The mechanical arm is reasonable in structural design, is specially used for the small-sized mechanical arm, is fixedly connected with the small-sized mechanical arm through the pipette connecting contact and the pipette electromagnetic mounting port, can effectively improve the pipetting efficiency and the pipetting precision of the mechanical arm, and saves the experiment time
