流路デバイス100の機能は大まかには下記のように説明される。
図2、図5(c)、図8、図9を参照した説明が行われる。まず、説明を容易にするために、貫通孔229および排出孔329のいずれの平面視上の輪郭(以下、単に「輪郭」と称す)も、平面視上で円形である場合が想定される。貫通孔229の輪郭は面2aの縁によって規定される。排出孔329の輪郭は分離デバイス3の平面視上の縁によって規定される。図8もかかる想定に則って描かれる。図8において排出孔329と流路39との境界は仮想線たる一点鎖線によって円弧として描かれる。
排出孔329は円形に限られず、楕円形であってもよい。輪郭329cには円を含む楕円形が採用され得る。貫通孔229は円形に限られず、楕円形であってもよい。輪郭229cには円を含む楕円形が採用され得る。導入孔129は円形に限られず、楕円形であってもよい。
