Abstract (en)

[origin: EP1419818A1] The apparatus (10) to move fluid samples in steps, using capillary forces, has a capillary channel (14) for the interconnected reaction chambers. At least two closed ventilation openings (38,40,42) are located at intervals along the channel, with channel connections (22,24,26) for fluid flows, and which divide the capillary channel into sections (44,46,48). The apparatus (10) to move fluid samples in steps, using capillary forces, has a capillary channel (14) for the interconnected reaction chambers. At least two closed ventilation openings (38,40,42) are located at intervals along the channel, with channel connections (22,24,26) for fluid flows, and which divide the capillary channel into sections (44,46,48). The ventilation openings are opened separately, to give flows between the channel sections. Each channel section has at least one chamber (50,52,54) in front of the ventilation connection, in the flow direction.
