Abstract: A moving device, applied in a nucleic acid extraction system and cooperated with a plurality of microtube components, the moving device includes: a workbench; a moving component, disposed on the workbench; a control element, disposed on the moving component and electrically connected to the moving component; a first motor, disposed on the moving component and electrically connected to the control element; a first rotating rod, connected to the first motor; a second motor, disposed on the moving component and electrically connected to the control element; a second rotating rod, connected to the second motor; and a telescopic component, disposed on the moving component corresponding to the first rotating rod and the second rotating rod, electrically connected to the control element, and movable between a first position and a second position.

Abstract: An electronic pipette real-time responsive to manual operation includes a pressing unit, a signal generator, a controller, a power unit and a drawing/draining unit. The signal generator senses a displacement stroke of the pressing unit by user and generates a displacement signal to the controller. The controller performs calculation on the displacement signal to generate a control signal for sending to the power unit. The power unit drives the drawing/draining unit according to the control signal. The amount and speed of the drawing/draining can be shown on a display of the controller.
