text: The pipette itself is an apparatus comprising following members (see Fig. 2).
  : pipette tip configured to be able to access and aspirate/discharge liquid from/into each of vessels, having
  ::a front end portion,
  ::a reservoir portion,
  ::a liquid passage
  :::connecting the front end portion and the reservoir portion,
  ::a separation region
  :::in the liquid passage subjected to an action of a magnetic field, and
  ::a mechanism
  :::for applying a negative or positive pressure to the interior of the pipette portion to draw or discharge a magnetic substance suspended liquid into or from the pipette portion
  :magnetic field Source
  ::arranged on the outside of and adjacent to pipette tip; and
  :magnetic field source driving device
  ::for driving the magnetic field source to apply or remove a magnetic field to or from the separation region from outside the liquid passage. When the magnet is brought close to the pipette tip, a magnetic field is applied; when retracted away from the pipette tip, that magnetic field is removed.
  A nucleic acid extraction apparatus incorporating Tajima pipettes typically consists of:
  :Above mentioned Tajima pipette,
  :Plurality of tubes.
  : Plurality of tube holder for above mentioned tubes,
  :Transport mean
  ::to transport Tajima pipette among that plurality of tubes (tubes are supported by tube holder), and
  :Control device
  ::for controlling abovementioned devices.
