Abstract: The present invention relates to a suction dispensing device having a removable tip, which can suction or dispense liquid by allowing a dispensing tip to be mounted thereon and can automatically remove the mounted dispensing tip, the device comprising: a driving base module which raises and lowers a movable plate; and a syringe operation module having at least one syringe installed therein so that when the movable plate rises from a reference position to a suction position, liquid can be suctioned therein, and when the movable plate returns to the reference position from the suction position, the liquid can be dispensed, wherein, in the syringe operation module, when the movable plate moves downward from the reference position to a tip removal position, a tip removal plate may be formed so that the dispensing tip forcefully engaged in the front end of the syringe can be removed.

Abstract: Provided is a cell culture system capable of mixing a medium for culturing animal or plant cells. The cell culture system includes a body, a movable plate including an accommodation space accommodating a culture bag accommodating a medium to mix the medium, and being tiltable in multiple directions by a central joint mounted at a first location of the body, a first actuator mounted between the body and a second location of the movable plate to move the movable plate, a second actuator mounted between the body and a third location of the movable plate to move the movable plate, and a controller for applying a control signal to the first and second actuators, wherein a first angle between a first reference line extending from the first location to the second location, and a second reference line extending from the first location to the third location is 120°.
