Abstract

A microchip device has at least one passage along which a liquid can be moved by applying a voltage to the liquid. The device includes a passage member (10, 12) in which the passage is formed and which has an aperture (20, 22). Additionally the device includes an electrode member (14) that comprises an electrode (42, 44) and that is separably engageable with the passage member. The device includes a reservoir in fluid communication with the passages for holding a liquid. The electrode member cooperates with the aperture so that the electrode is in fluid communication with the passage without the electrode member obstructing the opening of the reservoir.
