PURPOSE:To perform an operation such as selection and collection of necessary organism cell and the removal of dust, etc., by attaching a sucking and discharging pump to a cube having small holes on the side face, rotating the cube to suck a cell from a liquid phase and releasing the cell at the end of rotation. CONSTITUTION:A collection drum 6 is rotated in a Petri dish 3 holding a solution 4 containing organism cells. Sucking and discharging pumps 14a... are connected to connection holes 12a... connected to small holes on the side faces of the drum. When a small hole is immersed in the liquid phase, a negative pressure is applied to the small hole to suck a cell, which is released by applying a positive pressure to the small hole at the transfer end of rotation.
