<p>An automatically filled pipette apparatus according to the present invention has an effect of preventing the contents from being wasted by being discharged in the excessive amount by providing a certain amount of air toward a pipette assembly in which the content is discharged even a user applies an excessive control power. Provided is a pipette apparatus which comprises a pipette assembly (20) having the content be absorbed to be filled; a pumping assembly (30) arranged on the upper side of the pipette assembly (20), being relatively moved for the pipette assembly (20), and providing change in the pressure of a pumping space (81) to the pipette assembly (20); a bellows (40) made of an elastic material and connecting the pipette assembly (20) and the pumping assembly (30) being relatively moved; and a housing (50) including a thread (51) formed on the inner side to be coupled by a screw with of a thread (11) of a container (10), and having the pumping assembly (30) be fixed.</p> |
