ABSTRACT:
A micropipette usable for producing a biochip inclusive of DNA micro arrays capable of arraying and fixing droplets of a micro-volume on a substrate in a high density includes a main body, at least one cavity for storing a sample, at least one ejection port, a piezoelectic/electrostrictive element mounted on the outer surface of the main body, and at least one sample inlet port for supplying sample from the outside. A sample that is temporarily stored in the cavity is discharged from at least one ejection port, by virtue of the movement of the piezoelectric/electrostrictive element, to outside of the micropipette via a through hole in a nozzle portion formed in the pipette main body. The nozzle portion through hole has three or more projection radially protruding from the center of the through hole and having a specific shape.
