Description
実施の形態1では、液体移動抑制部として収容部の側壁面に複数の凹部が形成されているマイクロ流路チップについて説明する。
図1は、実施の形態1に係るマイクロ流路チップ100の構成を示す図である。図1Aは、マイクロ流路チップ100の平面図であり、図1Bは、マイクロ流路チップ100の側面図である。図2は、実施の形態1に係るマイクロ流路チップ100を構成する基板110の底面図である。
次に、本実施の形態に係るマイクロ流路チップ100を使用する場合における、液体移動抑制部170の機能について説明する。また、液体移動抑制部170の効果を説明するために、収容部150’の側壁面の底部に液体移動抑制部170が形成されていない比較例に係るマイクロ流路チップについても説明する。図4A〜Cは、比較例に係るマイクロ流路チップの収容部150’に液体が導入される過程を示す模式図であり、図4D〜Fは、実施の形態1に係るマイクロ流路チップ100の収容部150に液体が導入される過程を示す模式図である。なお、図4A〜Fでは、マイクロ流路チップにおける収容部150’、150の周辺部分のみを拡大して示している。また、ここでは、第1流路135を流れる液体が、第2流路145を流れる液体より先に収容部150’、150まで到達するものとして説明をする。
以上のように、本実施の形態に係るマイクロ流路チップ(液体取扱装置)100では、2以上の流路から1つの収容部に適切に液体を導入することができる。すなわち、2種類以上の液体(例えば、試料や試薬など)を扱う場合でも、適切に反応や分析などを行うことができる。
実施の形態2では、液体移動抑制部として収容部の側壁面に複数の凸部が形成されているマイクロ流路チップについて説明する。
本実施の形態に係るマイクロ流路チップ200では、収容部250内の液体移動抑制部270の数および形状が、実施の形態1に係るマイクロ流路チップ100と異なる。そこで、実施の形態1に係るマイクロ流路チップ100と同一の構成要素については、同一の符号を付してその説明を省略する。
次に、本実施の形態に係るマイクロ流路チップ200を使用する場合における液体移動抑制部270の機能について説明する。図7は、実施の形態2に係るマイクロ流路チップ200の収容部250に液体が導入される過程を示す模式図である。なお、図7では、マイクロ流路チップにおける収容部250の周辺部分のみを拡大して示している。また、ここでは、第1流路135を流れる液体10が、第2流路145を流れる液体20より先に収容部250まで到達するものとして説明をする。
以上のように、本実施の形態に係るマイクロ流路チップ(液体取扱装置)200では、2以上の流路から1つの収容部に適切に液体を導入することができる。すなわち、2種類以上の液体(例えば、試料や試薬など)を扱う場合でも、適切に反応や分析などを行うことができる。
