Abstract
The present invention relates to a rotary pipetting device comprising a plurality of pipetting assemblies and a driving motor. Each pipetting assembly comprises a shaft rod, a connecting portion, and a pipette tip; a return spring is mounted at the top of the shaft rod, and a gear is sleeved on the shaft rod; the connecting portion is disposed at the bottom of the shaft rod; the pipette tip is connected to the connecting portion. An output shaft of the driving motor is connected to a rotating gear, the rotating gear is engaged with a transmission member. When power is supplied to the driving motor, the power output of the driving motor drives the transmission member to rotate, thereby driving the gear on the shaft rod to rotate and causing the pipette tip to rotate.
