A biotip according to an embodiment of the invention moves a reaction mixture along a longitudinal direction under the force of gravity. The biotip includes a chamber formed of a transparent material and filled with a liquid having a smaller specific gravity than the reaction mixture and immiscible with the reaction mixture, and a seal that seals the chamber. The liquid has a volume resistivity of greater than 0 &OHgr;·cm and 5×1013 &OHgr;·cm or less. |
