ELECTROOSMOTIC FLOW PUMP SYSTEM AND ELECTROOSMOTIC FLOW PUMP

摘要

A projection (35) is formed on a pump body (24) of an electroosmotic flow pump (14a-14d) so as to face a communication hole (36) of a micro fluid chip (12). When the projection (35) and the communication hole (36) are fitted together, a first flow path (22) of the pump (14a-14d) and a second flow path (18) of the micro fluid chip (12) are communicated and the pump (14a- 14d) is fixed to the micro fluid chip (12). At the same time, the connection between the first flow path (22) and the second flow path (18) is sealed to prevent leakage of liquid (38, 40), gas (42), etc. to the outside.
