Description
前記流路の内壁面の少なくとも一部は、該流路の入口から出口までの全体に亘って、少なくとも一つの送液を遮断する疎水性を有する弁部を除いて親水性を有し、
前記弁部に、前記流体の界面張力を減少させるための電極と、前記流体を切断するため外気を導入する通気部が設けられていることを特徴とするものである。
該正負の二極の一方の電極が、前記疎水性の弁部に臨設されていることが好ましい。
前記出口区間及び前記外縁部のうち前記出口に隣接する周縁部に、前記流体の界面張力を減少させるための第二の電極が設けられていることが好ましい。
前記電極に電圧を印加することにより、前記流路中の前記弁部を疎水性から親水性に変化させて前記流体を送液し、電圧の印加を停止することにより、前記弁部を疎水性に変化させて前記通気部から外気を該弁部に導入して前記流体を一定量だけ分割することを特徴とするものである。
